Answer:

Step-by-step explanation:
The point-slope equation of a line is
,
where

and the point is

Let's find the slope.



We are asked to use the first point in the equation, so
and 
The equation is:

The slope intercept form might be: -2/3x+490
To find the answer, set up a system of equations.
Let x=adult tickets and y=senior citizen tickets.
x+y=556
22x+12y=8492
Change the first equation to make it easy to combine with the second equation.
y=556-x
Now substitute (556-x) for y in the second equation.
22x+12(556-x)=8492
Simplify and combine like terms.
22x+6672-12x=8492
10x=1820
x=182
182 adult tickets were sold, so to solve for the number of senior citizen tickets sold, subtract 182 from 556.
556-182=374
374 senior citizen tickets were sold.
