Question

Identify the lines that are perpendicular: y=-2 y=1/5x+3 x=-2 y+3=-5(x+2)

Answer 1

y=-2 and x=-2

y=1/5x+3 and y+3=-5(x+2)

Explanation:

1) the lines y=-2 and x=-2 are perpendicular (horizontal and vertical lines);

2) the lines y=1/5x+3 and y= -5(x+2) are perpendicular (the slope1*slope2= -1).
