BTW, I really need help! This is for a really important benchmark, and it's a little overdue.

If it's that important, you'd better figure out how to do it yourself.

So you are going to make me even more late by not helping, what you are here for?
Answered by
Ms. Sue
I do not know how to help you. A math tutor should be around in an hour or two.

Ms. Sue, in the future, please don't respond, especially telling me to do it on my own if you don't know. And I don't need a tutor. Especially this late. Thanks, tho.

If you don't need a tutor, why did you post on Jiskha?

Function Q:
(4, 0), m = 1/4.
Y = mx + b.
0 = (1/4)4 + b,
b = -1 = y-int.
Eq: Y = (1/4)x - 1.
Function R:
(x, y): (-4, 14), (3, 0), (5, -4).
m = (0-14)/(3-(-4)) = -14/7 = --2.
Y = mx + b,
14 = -2*(-4) + b.
b = 6 = y-int.
Eq: Y = -2x + 6.
(4, 0), m = 1/4.
Y = mx + b.
0 = (1/4)4 + b,
b = -1 = y-int.
Eq: Y = (1/4)x - 1.
Function R:
(x, y): (-4, 14), (3, 0), (5, -4).
m = (0-14)/(3-(-4)) = -14/7 = --2.
