(7 × 10-21) / (<span> 7.6 × 10-22) = 9.21 times greater</span>
OK.
Let g(x) = ax²
We have the point (3, 1).
Substitute x = 3 and g(x) = 1:
1 = a(3²)
9a = 1 |divide both sides by 9
a = 1/9
Therefore your answer is

Answer:
4
Step-by-step explanation:
we want y = mx + b
4x = 2y - 3
-2y = -4x - 3
2y = 4x - 3
therefore the gradient (slope) = the coeffecient of x, which in this case is 4
I think it would be 1.5% but I'm not completely sure
