anonymous · Answer

for this im not sure what the slope would be but i know to just plug the rest in after

abdullahm · Answer

The slopes of 2 perpendicular lines when multiplied would be -1.

anonymous · Answer

so -1/4  * 4/1

abdullahm · Answer

Lets say the slope for the line they want us to find is 'y', then:

$\sf\Large \frac{-1}{4} \times y = -1$

anonymous · Answer

hmm

anonymous · Answer

4/1

abdullahm · Answer

correct, so the slope if 4, because 4/1 = 4

abdullahm · Answer

What answer choice does that eliminate?

anonymous · Answer

a and b

anonymous · Answer

now i just plug them in again like the last one?

abdullahm · Answer

exactly :)

anonymous · Answer

c?

abdullahm · Answer

Correct $\ddot\smile$

anonymous · Answer
