This is what the graph should look like when you're using 2/3x=y-1 as the equation.
2 blocks = 1 minute
18 blocks = 9 minutes
60 blocks = 30 minutes
She already ran for 9 minutes. She needs to run 42 more blocks.
If we subtract 9 minutes from 30 minutes, we get 21 minutes. Therefore, she needs to run 21 more minutes.
To verify this, we check the proportionality.
2 blocks = 1 minute
42 blocks = 21 minutes
42 blocks / 21 minutes = 2 blocks per minute
Hope this helps!
