Answer:
y=2x-7
Step-by-step 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
