CCSS.8.EE.B.5

What is the line of best fit (use DESMOS)

• f(x)= 5x+1.82

• cannot be determined

• f(x)= 1.82x + 5.02

• f(x)= 1.1x + 4.2

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

• f(x) = 25.05x + 5.57

• f(x) = 5.57x + 25.05

• f(x) = -5.57x + 25.05

• f(x) = 5.57x - 25.05

What type of association does this graph have?

• positive 
• negative
• none
• all of the above
