Question

what is the equation for A line that passes through the point (0,12) is perpendicular to the line y=4x-6

Answer 1

y=(-1/4)x + b, perpendicular line has slope which is the negative inverse of 4. change the sign & flip it upside down, change 4 or 4/1 into -1/4

then plug in the point to solve for b, the y intercept

12= 0+b

b=12

y = (-1/4)x + 12 is the equation of the perpendicular line through the point (0,12)
