I think i know the answer to that question. just wait for a sec.
Answer:
y = 3/2x + 5/2
Step-by-step explanation:
From the second figure it can be seen that 25 + 144 = 169
This implies that 5^2 + 12^2 = 13^2
This is a right triangle with legs of 5 and 12 and hypothenus of 13.
it isn't possible to just give extra points in a simple and reliableway. anyways, let's starts.
a. is simple, just put the terms in order
r² +6r -5
because:

anything to the power of 0 equals 1,
because it's the same as r/r, and 5 * r/r = 5*1
b. same logic as above
a²b² -5ab +33
c.
-c³ +ab +d +9
d.
-9y^5 - 2x³y²z +4x² +10x +1
^5 = to the power of five, it's the fastest way to type it without the special math input tool.
hope it helps you
