Question

Identify an equation in point-slope form for the line perpendicular to y = -1/2x + 11 that passes through (4, -8)

Answer 1

y+8 = 2(x-4)

Explanation:

Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.

And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:

y-y1 = m(x-x1)
