amir records the number of customers who order hummus at his mediterranean café on saturday. the scatter plot shows his data and a line of good fit. based on the line of good fit, how many customers order hummus per hour? 5 17 20 35
Answer
Explanation:
Step1: Find two points on the line
Let's take two points on the line of best - fit, say (2, 40) and (4, 80).
Step2: Calculate the slope
The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Substituting $x_1 = 2,y_1 = 40,x_2 = 4,y_2 = 80$ into the formula, we get $m=\frac{80 - 40}{4 - 2}=\frac{40}{2}=20$. The slope represents the number of customers who order hummus per hour.
