Question

"The standard form of a linear equation is Ax+By=C. For each set of values given, tell if the linear equation represents a horizontal line, a verticle line, or neither.

A=2, B=2, C=2

A=0, B=5, C=0

A=-8, B=0, C=8

Answer 1

A=2 B=2 C=2 represents neither of the two.

A=0 B=5 C=0 is a horizontal line running parallel to the X axis.

A=-8 B=0 C=0 is a vertical line, with a fixed X co-ordinate.
