Answer:
D
You use algebra and solve it for y.
Step-by-step explanation:
4x-3y=18
3y=4x+18
y=4/3x +6
15(25-5a)=4-a
375-75a=4-a
Add 75a to both sides
375= 4+74a
Subtract 4 from both sides
371=74a
Divide both by 74
5.01=a
-2/3
first do y2-y1 over x1-x2
then it’ll be 2-4 over 5-2
coming out as -2/3
Juanita did make an error, she should have combined -4 and -5 to make -9
