I just found out something. You can do a simultaneous equation to find out x and y in question 11(a). I tried it and got the same answer. The method in the video seemed a bit confusing for me so I used the simultaneous equation method. Hope it helps! :)
I had the same doubt. It's nothing complicated. Imagine that you are drawing on the graph and you place a point on the x-axis at -2 and then another point on the x-axis at +6, so from -2 to +6 there are 8 boxes so the value is 8. The same goes for 4 also. It is the number of boxes from -1 to 3 on the y-axis, thus it is 4. Hope it helps! :)
