Question

Find the equation of the line passing through the point (1,−5) and perpendicular to y=1/8x+2

Answer 1

Answer: y= -8x+3

Explanation:

If it's perpendicular the slope is the negative reciprocal, so from 1/8 it would be -8/1, which is just -8. To find b plug in (1,-5) into y=mx+b which is slope intercept form, to get b=3.
