Q22.
9x - 2/3 y = -4
-2/3 y = -9x - 4
y = (-3/2) (-9x - 4) = (27/2)x + 6
That's a slope of 27/2 which means for every increase of 1 in x, y increases by 27/2.
Q23.
g(x) = (3/4) x + 5
Is that steeper than y=x? The function g has a slope of 3/4 and y=x has a slope of 1, which is more.
Answer: FALSE, g is less steep than y=x
