What is the line of best fit for this data? (1, 5)(2, 8)(3, 11)(4, 14)(5, 17)(6, 20)(7, 23)

The line of best fit is y = 3x + 2.

The points in the list fall in a straight line. All we need to do is find the slope and the y-intercept. Then, put them in the form of : y = mx + b

First, the slope. Our x-values are in order and our y-values are going up by 3. So, 3 is our slope.

Second, the y-intercept. The point (1, 5) is our first point. If he go down 3 and back to 0, we will have the y-intercept of 2.

You can graph these points and the equation to prove that it is correct.
