Question

Write the line perpendicular to y = (1/8) x + 2 through the point (1,-5). Write the final answer in slope-intercept form.

Answer 1

if the line is perpendicular the slope is the negative reciprocal

1/8 becomes -8

point slope form

y-y1 = m(x-x1)

y--5 = -8(x-1)

y+5 = -8x+8

subtract 5 from each side

y = -8x +3

this is in slope intercept form
