7-89.

The graph of the equation $2x-3y=7$ is a line.

1. Find the $x$- and $y$-intercepts and graph the line using these two points.

To find the y-intercept, substitute $0$ for $x$ and evaluate.

The $y$-intercept is $\left(0,-\frac{7}{3}\right)$.

Now do the same for the $x$-intercept, but substitute $0$ for $y$ instead.

2. If a point on this line has an $x$-coordinate of $10$, what is its $y$-coordinate?

Substitute $10$ for $x$ and evaluate for the value of $y$.
