The red line represents the line of best fit for the scatter plot. How many ice cream sales are expected if the temperature is 90°?

• 55

• 0

Name the equation that is represented by the graph.

• y=2x+4

• y=-2x+4

• y=2x-4

• y=-2x-4

Write the equation of the graph in slope-intercept form

Match the scatter plot to the equation that could represent the equation of its trend line.

• y = 3x

• y=4x-2

• y = -x + 5

• y = -5x

• The relationship is not linear
