Question

Find an equation for the line perpendicular to y = (-1/5)x + 4 and passes through the point (-6, -10). Write answer in slope intercept form

Answer 1

Explanation:

to make line perpendicular, the slope should be: slope 1 x slope 2 = -1

first, find slope 1 of y = (-1/5)x + 4, which is: m1 = -1/5

m1 x m2 = -1

-1/5 x m2 = -1

m2= 5

you should use formula for 1 point and 1 slope :

y-y1= m(x-x1)

y+10 = 5(x+6)

y+10 = 5x+30

y = 5x+20

Hope it helps.
