    hint: Rate of change is the slope

    2x-5y=15 solve for y to have the same form that one have

    well of course it is positive do you see any negaative sign there?

    2x-5y=-15 what do you do to solve for y?

    you need to solve for y to find the slope we want it to be of this form y=mx+b where m=slope and b is y intercept
