"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

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.

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
