Exercise 5 Page 137

Choose two ordered pairs from the table and calculate the slope by substituting them into the Slope Formula.

Undefined.

Practice makes perfect
Looking at the table, we can identify 4 ordered pairs. (5,-12), (5,-9), (5,-6), (5,-3) Note that there is no change in x. We can choose any two points from the table and use the Slope Formula. Let's use the points (5,-12) and (5,-9).
m = y_2-y_1/x_2-x_1
SubstitutePoints

Substitute ( 5,-12) & ( 5,-9)

m=-9-( -12)/5- 5
SubNeg

a-(- b)=a+b

m=-9+12/5-5
AddSubTerms

Add and subtract terms

3/0
Because division by zero is undefined, the slope of the line is undefined.
