Step-by-step explanation:
We have the following point
(2,100)
We know that the equation has a y intercept of 0 which means our equation looks like this
y=mx
We know that when x=2 y=100 so
100=2m
m=50

Answer:
There were 40 student tickets sold.
Step-by-step explanation:
First I set up equations to represent this situation.
4x+3y=380
x+y=105
x represents the adult tickets and y represents the student tickets.
I can solve this with the elimination method. I want to cancel out the x so I will multiply every term in equation 2 by -4.
4x+3y=380
-4x-4y=-420
Now I combine like terms.
-y=-40
I can divide the negative one from both sides.
y=40
