Answer:
the slope is 4/3
Step-by-step explanation:
the original slope is -12/-9, because to go from 15 to 3 you have to go left 12 times, and to get from 7 to -2 you have to go down 9 times. So now we have -12/-9, but since fractions numerator and denominator cant both be a negative, we turn it into positive 12/positive 9. Then we can simplify it by dividing it by 3 to get the slope 4/3.
