Write a prediction line (equation of line of best fit) for the points in the table:

Question

x 2 4 6
y 7 13 19


Show all work! List points then write an equation in y = mx+b form.

Use the prediction equation to predict the y value for x = 25.

Answer 1

note that the slope is 6/2 = 3
So, use the line y=3x+1
