Question

Write the equation of a line that is perpendicular to y=2 and passes through (-1, -3)

Answer 1

x = -1

Explanation:

since this is a horizontal line, the perpendicular line will be a vertical line of the form x = a

since we are given that the line should pass through (-1,-3), then the equation of the line is x = -1 (as shown in the graph)
