Exercise 88 Page 71

Substitute the given points into the Slope Formula.

0

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 ( - 2,3) & ( 8, 3)

m=3- 3/8-( - 2)

▼

Add and subtract terms

a-(- b)=a+b

m=3-3/8+2

Add and subtract terms

m=0/10

0/a=0

m=0

The slope of the line that passes through the given points is 0.
