To create a scatterplot using the provided data in Desmos:
1. Input the data points in the table into Desmos. Let's assume the table consists of two columns: "Calories Burned" and "Time Spent Working Out."
2. Plot the points on the scatterplot by clicking on the "+" icon and entering each data point.
3. Once all data points are plotted, click on the wrench icon to add a regression line to the scatterplot.
To find the regression equation in Desmos:
1. After adding the regression line, click on the equation of the line to display the regression equation in the form: Y = mx + b. The equation will represent the relationship between calories burned and time spent working out.
2. Use the regression equation to calculate the time needed to burn 600 calories by substituting 600 for Y in the equation and solving for X (time spent working out).
For example, if the regression equation is Y = 0.05X + 50, then:
600 = 0.05X + 50
550 = 0.05X
X = 550 / 0.05
X = 11,000 minutes
Therefore, according to the regression equation, someone would need to work out for 11,000 minutes or approximately 183.33 hours to burn 600 calories.

Now use Desmos to find the regression equation. Using this regression equation, how long should someone work out if they want to burn 600 calories
