Question

Find the equation of the line which passes through the point (-4,12) and is perpendicular to the given line. Express your answer in slope intercept form. The slope is -7

Answer 1

y = 1/7x + 88/7

Explanation:

y = mx +b

since it is perpendicular you have to get the negative reciprocal of the slope which is 1/7

y = 1/7x + b then you would plug in your points

12 = 1/7(-4) + b and then solve for b

12 = -4/7 + b

+ 4/7

88/7 = b

y = 1/7x + 88/7
