Question

What is the equation of the line that passes through the point (2, 3) and is perpendicular to the line y = –x – 3?

Answer 1

is it I assume you mean parallel and perpendicular to y = -2x though since y=-2 is a horizontal line passing through (0,-2) , (1,-2) and so on

Parallel: y = -2x-3

Perpendicular y = 0.5x-3

Answer 2

but, my options are:
y = –x – 1

y = –x + 5

y = x + 1

y = x + 5

Answer 3

what is the slope of the line y = –x – 3
