Question

what would you have to do to make the line y = 2x -7 steeper on the coordinate plane?

Answer 1

The slope, if increased, would make the line y=2x-7 steeper. If you were to increase the y intercept, you would just move the line, not tilt it. Suggest changing it to 4x-7 = y or 8x-7= y, if you increase the slope, it'll make it steeper.
