Exercise 15 Page 78

Substitute the given points into the Slope Formula.

There is no answer for this exercise

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

SubstitutePoints

Substitute ( -3,5) & ( 4,5)

m=5- 5/4-( -3)
