2. A linear model for the data in the table is shown in the scatter plot. (a) Which two points should you use to find the equation of the model? Circle the points on the graph.
(b) What is the slope of the linear model? Show your work
(c) What is the equation of the linear model in point-slope form?
(d) What is the slope-intercept form of the equation you wrote in Part (c)? Show your work.
(e) What is the equation for the least squares regression line? Round the values for a and b to three

step-by-step explanation:

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
