The y-intercept is 8.75.

#### Explanation:

Let's assume this is a straight line. So we know that the line follows the equation:

Where m is the slope and b is the y-intercept.

The problem give us:

First, let's solve for b:

Now, let's plug in numbers:

We can double-check by graphing the line:

graph{.5 x +8.75 [-14, 26, -2.24, 17.76]}

This does go through the point (1.5, 9.5).
