Answer:

y=2x-7

Explanation:

The equation we are looking for would be y=mx+b.

Currently, you are trying to find "m" and "b"

m is the slope, and you can find this slope by finding (11-(-5))/9-1), which is equal to 16/8, or 2. So, we now know m, or the slope.

To find b, we need to plug in one of our points to the equation. Let's use (9,11).

11 is the y value, so we input it to the y place. 9 is the x value, so we input into the x place.

11=2(9)+b

If we solve this, we get -7=b

So, your equation is y=2x-7
