Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 30

Step 2: Solve for x hits

1. Substitute [BLF]:                     30 = 0.15x - 1.5
2. Add 1.5 to both sides:            31.5 = 0.15x
3. Divide 0.15 on both sides:     210 = x
4. Rewrite:                                   x = 210

Remember that this is a prediction. According to the best line of fit, we would need 210 hits to get 30 home runs.
