Answer:
B
Step-by-step explanation:
In order for something to be a function, they must not have repeating x-values. Looking at the answer choices provided, B is the only answer that does not have repeating x-values.
Answer:
y=-2x+4
Step-by-step explanation:
y=mx+b where m is the slope b is the y-intercept.
Plug in values to get:
y=-2x+4
<span>5t=3b+660....and ... 2t+5b=450
from the first we can see that t=(3b+660)/5 and using this value in the second...
(6b+1320)/5+5b=450 making all have common denominator..
6b+1320+25b=2250
31b=930
b=30...and since 2t+5b=450
t=150</span>
We will be using the Point Slope formula which is 
The information we are given is that m = -4 and the point is (2,-5), so we can input it into the equation.
This simplifies into 
Then we can subtract 5 from each side to get the answer:
