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?
