Exercise 82 Page 438

Substitute the given points into the Slope Formula.

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 ( 2,-5) & ( 3,1)

m=1-( -5)/3- 2
