Finding the Slope of a Line
Slope
The slope of a line tells you how steep the line is.
Formula
To find the slope of a line, we take the change in y divided by the change in x:
Some call this equation "rise over run":
The slope of a line tells you how steep the line is.
Formula
To find the slope of a line, we take the change in y divided by the change in x:
Therefore, in order to find the slope, you divide the difference of the y-coordinates of a point or a line by the difference of the x-coordinates.
Problem #1
What is the slope?
Step 1
Select any 2 points on the line
Point 1:
(-1, -2)
Point 2:
(2, 2)
Step 2
Put those point into the slope formula
Therefore:
= 4/3
Answer: The slope of the line is 4/3
Problem #2
What is the slope?
Step 1
Select any 2 points on the line
Point 1:
(-2, 5)
Point 2:
(-4, 4)
Step 2
Put those point into the slope formula
Therefore:
= -1/-2 which equals: 1/2
Answer: The slope of the line is 1/2
