What is the slope of a line perpendicular to the line whose equation is 12x-9y=135

Step-by-step explanation:

First, we need to isolate y.

1. Subtract 12x from both sides.

-9y=-12x+135

2. Divide by -9 in order to isolate y.

3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is , so the reciprocal and opposite (flip and change the sign) slope would be .

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
