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": 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
