Movie tickets cost $12 for adults and $8 for kids at a movie theater downtown. The equation 12x + 8y = $72 represents how many many adults (x) and children (y) can go to the movies for $72. Find the y-intercept of this equation and explain what it means.
y intercept = 9. This means that 9 children can go to the movies for $72.00.

Will this line rise or fall?
-4y = 8x +12
Negative slope so it will fall.
