Hello! The formula for finding slope is y2 - y1/ x2 - x1. This means that you subtract the first x and y-coordinates from the second x and y-coordinates. (-2, 3) is coordinate 1 and (4, -1) is coordinate 2. Let's find what each number would be.
-2 = x1
3 = y1
4= x2
-1 = y2
So then, we would set the formula up like this: -1 - 3/ 4 - (-2). Now, let's subtract. -1 - 3 is -4. 4 - (-2) is 6. -4/6 is -2/3 in simplest form. There. The slope of the line is -2/3.
Note: When you subtract a negative number, you are actually adding. So, if the expression is 4 - (-3), the answer is 7, because you add 3 to 4.
