Answer:
The answer to your problem is b because if she wants to spend 20 minutes on the piano and she has 50 minutes until dinner than she would have 30 minutes on the computer.
Step-by-step explanation:
Use y2-y1/x2-x1
So 0-5/3-2
-5/1= m= -5
Then plug it into y=MX+B
0= -5(3)+b
0= -15+b
b=15
y=-5x+15
So I hope this helps but I'm not sure how to plug it into that's equation. The rest of my work is rigt
