Linear Equations: Finding the Slope of a Line Given Two Points Quiz
Quiz Overview
Description
To find any equation of a line, the slope of the line must be found. When two points (x1, x2), (y1, y2) are given and the equation contains these two points, the first step is to find the slope of the line.
This is the equation to find the slope (m):
m - rise/run (y2-y1)/(x2-x1)
Example:
points (5, -7) and (7, 5)
x1 = 5; x2 = 7; y1 = -7, y2 = 5
(5 - (-7)) / 7 - 5
12 / 2
m = 6
For each set of points provided, find the slope (m). You will need a calculator and scratch paper. Select the best answer from the choices.
