Write the equation of a line that passes through (2.-7) and is parallel to y = 3

Question

Equation of a line that passes through and is parallel

Answer 1

y=3 is a horizontal line with slope zero

so line parallel to y=3 must also be a horizontal line with slope zero and a constant value of y.

since the line passes through (2,-7), the equation of that line must be y=-7.
