To find the y int, sub in 0 for x and solve for y
y = 1/3x - 6
y = 1/3(0) - 6
y = -6.....so the y int is -6 or (0,-6) <==
to find the x int, sub in 0 for y and solve for x
y = 1/3x - 6
0 = 1/3x - 6
-1/3x = -6
x = -6 / (-1/3)
x = -6 * -3
x = 18....so the x int is 18 or (18,0) <==
Set up 2 equations:
Total items sold: x + y = 300
This gets rewritten as x = 300-y
The second equation is for total amount made:
2.50x + 1.50y = 522
Replace x in the 2nd equation with the value of x from the first one:
2.50(300-y) + 1.50y = 522
Simplify:
750 - 2.50y + 1.50y = 522
Combine like terms:
750 - y = 522
Subtract 750 from both sides:
-y = -228
Divide both sides by -1 ( to make y positive)
y = 228
Now replace y in the first equation to solve for x:
x+ 228 = 300
Subtract 228 from both sides:
x = 72
He sold 72 bags of popcorn and 228 sodas.
It should be 8 if it is 5-5 which gives you 0.
Or it could be (5x5)-5=20+8=28.

Answer:
(2 1/4, 1 1/2) A
(-1 1/4, 1 1/2) B
(-2 1/2, 1/4) C
Step-by-step explanation:
We can determine that each tick mark represents 1/4 based off the given numbers. Now we just determine the points.
(2 1/4, 1 1/2) A
(-1 1/4, 1 1/2) B
(-2 1/2, 1/4) C
