solution,
slope(m) = y2-y1/ x2-x1
= 4+7/1+3
=11/4
I hope this is correct, the formula can be wrong so pls double check if u have formula.
So Kalinda starts with $25. Then she spends $14.28. This means you subtract since she spends it. Next, she shares $2.65. Again, use subtraction. The remainder is your answer. Or you can add 14.28 to 2.65 and then subtract that from 25.
The simplest form is 2 1/4
