Based on the line of best fit, you can use the equation of the line to predict the length of a catfish that weighs 37 pounds. If the equation of the line is in the form of y = mx + b, where y represents the weight and x represents the length, then you can plug in 37 for y and solve for x.
So, if the equation of the line is y = 0.8x + 10, you would plug in 37 for y:
37 = 0.8x + 10
Subtracting 10 from both sides:
27 = 0.8x
Dividing by 0.8:
x ≈ 33.75
Therefore, based on the line of best fit, you could predict that a catfish that weighs 37 pounds would be approximately 33.75 inches in length.
Colton decides to research the relationship between the length in inches and the weight of a certain species of catfish. He measures the length and weight of a number of specimens he catches, then throws back into the water. After plotting all his data, he draws a line of best fit. Based on the line of best fit, what would you predict to be the length of a catfish that weighed 37 pounds?
