How do I find the slope of two points?
How do I find the slope of two points?
There are three steps in calculating the slope of a straight line when you are not given its equation.
- Step One: Identify two points on the line.
- Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
- Step Three: Use the slope equation to calculate slope.

What is the standard form of numbers?
standard form is the usual way of writing numbers in decimal notation, i.e. standard form = 876, expanded form = 800 + 70 + 6, written form = eight hundred seventy six.
Are you supposed to simplify slope?
Yes. The simplified version is best. A slope of 5/10 and 1/2 will contain the exact same coordinates on the line but one is easier to read and graph. If you have graphed a function, the slope at any point on the graph tells you the rate of change of the function at that particular point.
What does it mean if a slope is 0?
A slope of zero means that there is a constant relationship between x and y. Graphically, the line is flat; the rise over run is zero. Figure 3. Slope of Zero.
What does a 0 slope look like?
‘ When the ‘rise’ is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it. It will look like ‘y = something.
What does it mean if the slope is a whole number?
Slopes can be whole numbers or fractions and either positive or negative. All slopes can be converted to a fraction form that tells you how much the line changes in the y direction over how much the line changes in the x direction.
What do you do when the slope is a whole number?
If the slope (m) is a whole number, like 2, you still interpret it as a fraction (2/1). Remember that slope can be interpreted as rise/run, where the numerator is how many places you move up or down and the denominator is how many places you move left or right.
Do you simplify slope to a whole number?
If you set the rise over the run, you get a fraction that describes the slope. Sometimes this fraction can be further simplified by dividing the numerator and the denominator by their greatest common factor. If the result is one, drop the denominator and express the numerator as a whole number.
What does Standard Form mean?
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).
What are the four different types of slopes?
Slopes come in 4 different types: negative, positive, zero, and undefined. as x increases.
What is the slope in standard form?
When we find slope in standard form, we take the A term, divide by B, then change the sign (or we just say -A/B. In this example, we have -3/-1, which is the same as 3/1, or 3.
What does C stand for in standard form?
Standard Form: the standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. Discussion. The standard form of a line is just another way of writing the equation of a line.
Do vertical lines have a slope of zero?
The slope of a line is change in Y / change in X. The slope of a horizontal line = 0, not undefined. The slope of a vertical line = undefined.
How do I convert standard form to slope intercept form?
Going From Standard Form to Slope-Intercept Form
- A standard form equation is when it is set up.
- Ax + By = C.
- 6x + 2y = 4.
- A slope-intercept form equation is when it is set up y=mx+b.
- Y = – 3x + 2.
- 4y = -8x + 16 then divide all by 4.
- y = -2x + 4 slope form.
- Example 2:
How do you identify a slope type?
From the previous section, you have discovered that there are four types of slope.
- postive slope (when lines go uphill from left to right)
- negative slope (when lines go downhill from left to right)
- zero slope (when lines are horizontal)
- undefined slope (when lines are vertical)
What line has a slope of 0?
horizontal line
Can you have a slope of 0 6?
An undefined slope means a vertical line. The equation of the vertical line passing through (0,6) is x=0 . The y axis has the equation x=0 too, so the line and the axis intercept at all points of the y axis.
What if the slope has a 0 on top?
When the 0 is on the “top” of the fraction, that would mean that the two y-values are the same. Thus that line is horizontal (slope of 0). If the “bottom” of the fraction is 0 that means the two x-values are the same. Thus that line is vertical (undefined slope).
What is B and C in standard form?
The standard form of a line is simply a special way of writing the equation of a line. The standard form is just another way to write this equation, and is defined as Ax + By = C, where A, B, and C are real numbers, and A and B are both not zero (see note below about other requirements).
