We have the expression:

And want to evaluate in y=5, this means we have to replace y in the expression for 5 and calculate the value of the expression, so:

The expression is 30 when y=5.

Look at the coordinates. They are both negative. (-5,-1)
Let me plot all the coordinates so you can see:
Joe= (-3,4)
Dan= (1,4)
Roy= (2,-3)
Lee= (-3,-4)
The only person with coordinates that are both negative is Lee.
"C" is the answer. Lee.
I hope this helps!

Answer:
3y=4x
y=4x/3
4x/3=x+3
x/3=3
X=9
y=12
(9,12) this is the answer
To find the number of miles Erma can drive, you will write and equation and solve it to find the amount of miles that can be driven on $600 over the 1600 miles that are allowed.
Daily rate + cost per mile over 1600 = total cost
(65 x 8) + 0.24m = 600
520 + 0.24m = 600
-520 -520
<u>0.24m </u>= <u>80</u>
0.24 0.24
m = 333.33... miles
The maximum number of whole miles she can drive would be 1933 miles (1600 + 333).
