Question

Create a data set describing two variables, with at least five data points, that has an equation for the line of best fit of y = 2x + 25. Show all your work for full credit.

Answer 1

X = 2, 4, 6, 7, 9

Y = 29, 33, 37, 39, 43

Explanation:

Given a best fit line of :

y = 2x + 25

Take points X as :

X = 2, 4, 6, 7, 9

X = 2

y = 2(2) + 25 = 4 + 25 = 29

X = 4

y = 2(4) + 25 = 8 + 25 = 33

X = 6

y = 2(6) + 25 = 12 + 25 = 37

X = 7

y = 2(7) + 25 = 14 + 25 = 39

X = 9

y = 2(9) + 25 = 18 + 25 = 43
