Answer

Answer:

(a) increase (b) positive (c) 25 (estimated value by looking at the line - of - best - fit at x = 8)

Explanation:

Step1: Observe the scatter - plot trend

As x (number of hours worked) increases, y (amount of money spent) generally moves upwards.

Step2: Determine the correlation type

Since y increases as x increases, it is a positive correlation.

Step3: Estimate from the line of best - fit

Locate x = 8 on the x - axis and find the corresponding y - value on the line of best - fit, which appears to be around 25.
