Question

Which of these equations describe a line that is parallel to the y-axis, and passes through (-2.3) A. y=-2x+3 B. Y=3 C. X= -2 D. x=3

Answer 1

The y-axis it's a vertical line, so is represented by x=0.

Then, a parallel line to this one has to be vertical too, and if it passes thorugh (-2, 3). The equation of the parallel line would be x=-2.

Let me explain with a graph:
