Question

if you were to write the equation of the line of best fit, what would the y-intercept be?
about 0
about 200
about 100
about 50

Explanation:

Step1: Analyze the graph's y - intercept

The line of best fit in the scatter plot: when we look at the y - axis (which represents sales, I assume) and the x - axis (temperature). The y - intercept is the value of y when x = 0 (temperature = 0°C). From the graph, when we extrapolate the line of best fit to x = 0, we can see that the y - value (sales) is around 200.

Step2: Compare with options

We have options: about 0, about 200, about 100, about 50. From our analysis of the graph's line of best fit at x = 0, the y - intercept is about 200.

Answer:

1. about 200
