Answer:
2
Step-by-step explanation:
If by gradient you mean slope....parallel lines have the same slope
rearrange equation to get in y = mx + b format
-2x + y - 5 = 0
y = 2x + 5
Slope is 2
I believe the first one is p^2-3p+7p-21 and the second one is9a^2-3ab-3ab+b
Factor
(x+7)(x-2)
Proof
7-2=5
7*-2=-14
Zeros
x+7=0
x=-7
x-2=0
x=2
Final answer: C
