Question

Which equation represents the line that passes through C(2,4) and is perpendicular to the graph of y=1/3x-1?

Answer 1

Explanation:

y=-3x + b the slope is the negative inverse of 1/3

4=3(2) + b

b =-2

the equation is

y=-3x - 2

slope is the negative inverse. You find the y intercept, b, by plugging in the point (2,4) to get 4=3(2)+b
