22-(7+5) = 10
10-3 = 7
X=7
Towards the north west i.e in the positive y-axis and negative x-axis

thats the slope, you can also get a decimal out of it
D--because it has y^2 in the equation and to isolate y you have to take the square root, the graph is going to be curved rather than linear.
6 + 3y = 4y +2
3y - 4y = 2 - 6
-y = -4
y = 4
hope that helps :)
