Question

Write an equation of the line that passes through (7,10) and is perpendicular to the line y=1/2x-9

Answer 1

Slope of perpendicular line is the negative reciprocal of slope of original line so -2, use the and the point of intersection to write equation for perpendicular line using point slope formula

y-10 = -2(x-7) evaluate and write in y = mx + b form.
