Exercise 5 Page 321

Substitute the given points into the Slope Formula.

Undefined.

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

SubstitutePoints

Substitute ( 6,-4) & ( 6,6)

m=6-( -4)/6- 6

a-(- b)=a+b

m=6+4/6-6

Add and subtract terms

m=10/0

Division by zero is undefined, which means that the slope of the line is also undefined. This will be the case for any vertical line.
