Heather used a graphing utility to find the equation of the line of best fit in this scatter plot.
After reading equation of the line from the graphing utility, Heather wrote in her notebook that the line of best fit is represented by the equation y = 0.77x + 1.34.

Heather likely an error when writing the equation of the line in her notebook because the slope and the y-intercept of the equation she recorded.
