For #1-3, tell whether x and y show a positive correlation, a negative correlation, or relatively no correlation.

A.9

For #4-9, use your Desmos graphing calculator to find the equation of the line of best fit in slope intercept form (y=mx+b). Round slope and y-intercept to the nearest tenth. If your answer isn't showing as correct, check with me and we will see if it is calculator differences...

A.9

In the following problems (Number 8 - 19), find the equation for the line of best fit. Then evaluate it for the given x or y values. Round to the nearest tenth!

A.9

Use the data in the chart below for problems 20-22.
