Choose the description of the graph of the equation x = -8

a. A horizontal line through the -8

b. A horizontal line through the 8

c. A vertical line through the -8

d. A vertical line through the 8

Grab a piece of graph paper (or just make one with a few marks) and graph y of any value you choose and -8 for x. What kind of line do you get?
