Exercise 3 Page 78

Substitute the given points into the Slope Formula.

-1

Practice makes perfect
We can calculate the slope by substituting the given points into the Slope Formula. m = y_2-y_1/x_2-x_1 Note that it does not matter which point we choose to use for ( x_1, y_1) and ( x_2, y_2), since the result of using the Slope Formula will be the same.
m=y_2-y_1/x_2-x_1
m=2- 4/4- 2
m=-2/2
m=- 2/2
m=-1
The slope of the line that passes through the given points is - 1.
