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).
