Write the equation of a line that is perpendicular to x = 3 and that passes through the point (0,−4)

Question

im very stumped on this questoion please help

Answer 1

The line that is perpendicular to x=3 (a vertical line) will be a horizontal line with zero slope and thus a constant y value. Since it passes through the point (0,-4), the equation of that line will be y=-4.

Answer 2

y=-4

lines perpendicular to x=3 are any line with a flat horizontal slope, with y= some constant

if it passes through (0,-4) then y=-4 is the only possibility.
