Question

Need help w/ #2.
I forgot how to do this.

Answer 1

The equation for a graph is y=mx+b, with m being the slope

In the given equation, -0.25 is the slope of the given line
This can also be written as -
`(1)/(4)`

To find a perpendicular graph, you find the reciprocal of the slope
To do this, you switch the numerator and the denominator

Your final answer will be:
-
`(4)/(1)` which simplifies to -4
