Answer: y = 8x +1
If you put the gradient (8x) into a fraction, it would be 8/1.
As for the rest, they would be: 2/3, -4/1 and 1/7.
Using the rise/run method, the fraction that has the highest ‘rise’ number will be steeper.
The fraction that has the highest rise is 8/1, so that has the steepest slope out of the rest.
