What is the domain and range of a graph?

The domain of a graph is how far left to right your solutions go and the range is how low to high your solutions go.

What is the vertical line test?

The vertical line test is used to determine if a line on a graph is a function. If the vertical line crosses more than one point, it is not a function.

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.
