Question

Which is the equation of the given line?

A.
x = –4

B.
y = –4

C.
y = –4x

D.
x = 4

Answer 1

The equation should be in the form y=mx+b where m is the slope and b is the y-intercept. Note that the equation for slope is rise/run. There is no rise, is there? 0 divided by any number always equals 0, so therefore the slope itself is 0. That means there will be no mx term in your answer. It all depends on the y-intercept. Can you see what the value for the y-intercept is?
