Question

Choose the equation of the line passing through the point (1, -5) and perpendicular to y = 1/5x - 10.

y = 5x + 10

y = 5x

y = -5x - 10

y = -5x

Answer 1

A line is perpendicular to another when the slope is inverse and opposite.

Answer 2

If \[y=mx + b\] where mx is the slope and b is the y intercept, then what would a perpendicular slope be?

Answer 3
