Answer:
18:30
or a more simplified version is
3:5
The slop-intercept form:

m - slope

b - y-intercept
We have (0, 2) and (4, -1).
Substitute:

(0, 2) → y = 2 is y-intercept. Therefore b = 2.
Answer: 
Reflect over x=-3 if that's what you mean
Answer:
V = 26d^2 + 624d
Step-by-step explanation:
Volume = Width x Depth x Height
V = 26 (d) (d+24)
Now distribute 26
V = 26d(d+24)
Then distribute 26d
V = 26d^2 + 624d
