Question

A data set consists of the following data points:(3, 5), (5, 8), (6, 13)The line of best fit has the equation y = 2.5x – 3. What does this equation predict for a value of x = 3?

Answer 1

For this case we have the following equation:
y = 2.5x - 3
For x = 3 we have:
y = 2.5 (3) - 3.
Rewriting:
y = 7.5 - 3.
y = 4.5
Therefore, the ordered pair that predicts the line is:
(x, y) = (3, 4.5)
Answer:
this equation predict for a value of x = 3:
(x, y) = (3, 4.5)
