Wanda makes breakfast on Saturday mornings, and she enjoys trying out new muffin recipes. This scatter plot shows the number of ingredients in some of her favorite muffin recipes and the number of times she used each recipe over the past year. The scatter plot also shows the line of best fit.

Question

The equation for the line of best fit is y=
–
0.75x+10. According to the equation, which of these statements is true?

Answer 1

According to the equation y = -0.75x + 10, the coefficient of x is -0.75. This means that for every additional ingredient used in the muffin recipe, the number of times Wanda used the recipe decreases by 0.75. Therefore, the statement that is true is: The more ingredients Wanda uses in a muffin recipe, the less likely she is to use that recipe frequently.
