Find the equation of the line using the point-slope formula. Write the final equation using the slope-intercept form. perpendicular to 9y = x − 4 and passes through the point (−2, 1)

Answer 1

9y = x - 4

y = (1/9)x - 4/9

Then the perpendicular line has slope -9

B = y - mx = 1 - (-2)(-9)

= 1 -18

= -17

y = -9x -17
