How can we use the graph? The equation 25x+10y=150 is in standard form.

The standard form of a linear equation is Ax+By=C

where A, B, and C are integers, and A and B are not both equal to 0.

What information does the standard form give you?

With standard form, you can more clearly see constraints.
Hanna can spend $150. This is a constraint.

You can also more clearly see combinations that will make the equation true in the context of the situation.

You can also see the y-intercept AND the x-intercept.

[The intercepts are where the line intersects the axes.]

Click points you see on the graph to find the following:

(1) Find the x-intercept and explain its meaning
(2) Find the y-intercept and explain its meaning
(3) Find a combination of reserved tickets and general admission tickets that makes sense in this situation.
