Question

Find the equation of the line that is perpendicular to y = -½x – 9 that goes through (-3, 0).

Answer 1

Answer: y=−5x−15

Explanation:

Find the negative reciprocal of the slope of the original line and use the point-slope formula y−y1=m(x−x1)

to find the line perpendicular to y=1/5x+9.
