Question

“Write a linear equation that is perpendicular to 2x-5y=5 and passes through the point (2,-9).

Answer 1

Okay so you are correct with the gradient of the perpendicular line it is -5/2 however the equation is not y= -5/2 -1 because it is a new Line and has a new y-intercept therefore its Y=-5/2 + C but you have corrected that when doing the formula and have got the right answer
