The scatterplot shows the number of housing units in 2010 and 2018 for each of 11 US states. A line of best fit with equation y=ax, where a is a constant, is also shown. A point lies above this line if and only if it represents a state with an increase in housing units from 2010 to 2018 greater than 7%. What is the value of a?

A data set consists of the following data points:(3, 5), (5, 8), (6, 13)The line of best fit has the equation y = 2.5x – 3. What does this equation predict for a value of x = 3?A.7.5B.6C.9D.4.5

Leah manages an ice cream store. She wants to see if there is a relationship between the number of ounces of ice cream for each size and  the number of ice creams sold. For one month Leah counted the number of each size of ice cream sold and put her data in the chart below.Size of Ice Cream Ounces of Ice Cream Number Sold in One MonthKid's Size 2 11Small 4 29Medium 6 52Large 8 45Super Size 12 12 Leah created the scatterplot below.Which of the following interpretations does this scatterplot best support?Group of answer choicesThe negative quadratic trendline is the best choice for this data because it looks like the medium size was the most frequently purchased (the vertex) and both the kid's size and the super size were purchased less frequently.The positive quadratic trendline is the best choice for this data because it looks like the medium size was the most frequently purchased (the vertex) and both the kid's size and the super size were purchased less frequently.The decreasing exponential trendline is the best choice for this data because purchases decreased exponentially as the ounces increasedThere is no relationship between the ounces of ice cream and the number sold.A linear trendline with a positive slope is the best choice for this data because it is the simplest model and because customers purchased more ice creams as the number of ounces increased.
