Find the equation of the line

Question

Find the equation of the line that gies through (- 5, - 4) and is perpendicular to x = - 13. Write in the form y = mx + b.

Answer 1

x = -3 is a vertical line. The line perpendicular is a horizontal line in the form y = k.

If the line must pass through (-5, -4) then k = -4

y = 0x - 4
