What is the slope for (0, 4) and (5, -7)

-11/5

So to find the slope of those points you would want to take the difference of the Y points (the 2nd number in each pair) and put that over the difference of the X points (the 1st number in each pair).
Slope = (4 - -7) / (0-5)
Then the answer would be -11/5

-11/5 or -2.2. I hope this helps
