Hey!
------------------------------------------------
They already give us the slope, so we can solve the y-intercept.
We can use (3, -2).
y = 8x + b
-2 = 8(3) + b
-2 = 24 + b
-2 - 24 = 24 + b - 24
-26 = b
------------------------------------------------
Hence, the answer is

Hope This Helped! Good Luck!
Answer:
Step-by-step explanation:
If student ticket = 215 then 215 x 3 = 645$
Remaining tickets = 522 - 215 = 307
So adult tickets = 307 x 4 = 1228$
Total amount = 1228 + 645 = $1873
Answer:
y = 2x
Step-by-step explanation:
y=mx+b
m=2
x=2
y=4
4=2*2 + b
b = 4 - 4
b = 0
y = 2x
