As the x values go up by 1, the y values go down by 1 so the gradient is -1. Korede,
(0,-1) means when x=0, y=-1 so the intercept is -1.
As the x values go up by 1, the y values go down by 1 so the gradient is -1.

Eg 4% interest on a savings account means the % goes from 100 to 104. 104% is 104/100 or 1.04 With depreciation or sale discounts, work out what is left eg if there's 20% off, then you pay 80% or 80/100 or 0.8 Reverse percentages are a bit harder but they start off the same way. If bills go up by 15% then the new percentage is 115%. If you are given the new bill cost, then that represents 115% not 100% so you need to scale it down back to 100% to find out what the original was. Hope that helps! Hi Korede,
