Question

Which equation represents the line that passes through the point (7, -12) and is perpendicular to the y-axis?

y = 7
y = -12
x = 7
x = -12

Answer 1

perpendicular to the y-axis means that it is a y=number
with no x in the equation

the point is given in the (x, y) form
(7, -12) which means the y value is -12

this means that your answer/equation should be
`y = -12`
