Exercise 60 Page 491

Substitute the given points into the Slope Formula.

8

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,-7) & ( 4,1)

m=1-( -7)/4- 3

Add and subtract terms

a-(- b)=a+b

m=1+7/4-3

Add and subtract terms

m=8/1

a/1=a

m=8

The slope of the line that passes through the given points is 8.
