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

• y = 25.05x + 5.57

• y = 5.57x + 25.05

• y = -5.57x + 25.05

• y = 5.57x - 25.05

The graph above shows a line of best fit for data collected on the distance bicyclists have remaining in relation to the amount of time they have been riding.  What is the equation of the line of best fit?

• y = -25x + 170
• y = 25x + 170
• y = -(5/8) x + 170
• y = (5/8) x + 170
