The table shown is comparing a person's foot length to their height in cm. Calculate a line of best fit.

• f(x) = 25.05x + 5.57
• f(x) = 5.57x + 25.05
• f(x) = -5.57x + 25.05
• f(x) = 5.57x - 25.05

Determine the Correlation Coefficient and decide whether it is weak, moderate, or strong.

• -0.19 weak
• -0.19 moderate
