I want to double check my answer regarding the following math problem: Write an equation in the slope intercept form if possible: for the line which is at (0,-3) and is perpendicular to x - 2y = 7 My equation is: x-2y=7 x=2y+7 2y+y=x 2y/2 = x/2 - 7/2 Y intercept is x/2 - 7/2 Now I'm lost as far as the slope is concerned Please help
