If (-2,3) and (1,1) are two points on a line how do you find the equation

Use the slope formula to find the slope. This will be the m in y=mx+b. The b will be your y intercept. Find this by substituting your coordinates for x and y of your now y=mx+b. If you are looking for the answer rather than how to do it, it is y=-x+. This is by my math. Try it yourself.
