Answer:

y = -3/2x + 2

Explanation:

We want it in the form y = mx + b. First plug it into the equation
(y_(2)-y_(1) )/(x_(2)-x_(1) ) and get -9/6. This can be simplified to -3/2, so now we have the slope. y = -3/2x + b. To find b plug in one of those points. I chose (2,-1). Now we have

-1 = -3/2(2) +b. Solve this and get 2 = b. We can now make our full equation.

y = -3/2x + 2
