How: - As you can see the line goes through the y axis at 2- so we can substitute the c in y=mx + c for 2 - To find the gradient use two points on the line and count across and up, I used (-4,-6) and (0,2) which was 2 across and 4 up: 4 divided by 2 is 2 giving us the gradient to substitute the 2 as m into y=mx+c
