Answer:
$2.25
Step-by-step explanation:
Let "b" be the price of 1 brownie and "c" the price of 1 cookie.
At a bake sale, a student spent $11.00 buying 3 brownies and 5 cookies. Symbolicaly,
3 b + 5 c = 11.00 [1]
His friend spent $3.95 buying 1 brownie and 2 cookies. Symbolicaly,
1 b + 2 c = 3.95
b = 3.95 - 2c [2]
If we replace [2] in [1], we get
3 (3.95 - 2c) + 5 c = 11.00
11.85 - 6c + 5c = 11.00
c = 0.85
If we replace c = 0.85 in [2], we get
b = 3.95 - 2 (0.85) = 2.25

Similarly to the last graph that decreased, this one increases, so you have to see where the line points upwards into the right top corner
CD
I think my answer is a because it can’t be B and it can’t be C and it can’t be D so my answer is a
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
