## anonymous one year ago Choose the equation of the line passing through the point (-1, 7) and perpendicular to y = -one fourthx - 5. Choose one answer. a. y = -4x - 11 b. y = -4x - 3 c. y = 4x + 11 d. y = 4x + 3

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

3. AbdullahM

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

4. anonymous

so -1/4 * 4/1

5. AbdullahM

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

6. anonymous

hmm

7. anonymous

4/1

8. AbdullahM

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

9. AbdullahM

What answer choice does that eliminate?

10. anonymous

a and b

11. anonymous

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

12. AbdullahM

exactly :)

13. anonymous

c?

14. AbdullahM

Correct $$\ddot\smile$$

@AbdullahM do you know anything about correlations?
