Jake thinks that if you add the coordinate \((20, 32)\) to the data set, the y-intercept of the red line of best fit will be higher on the y-axis. Elliot thinks that if you add the coordinate \((20, 32)\) to the data set, the y-intercept of the red line of best fit will be lower on the y-axis. Whom do you agree with and why?

In this section, we will review how to write linear equations based on given information (two points, slope and point, parallel or perpendicular to a line, etc.) and how to use technology to approximate a line of best fit for a set of data.
Write linear equations using slope-intercept form, point-slope form and standard form.
