A survey was distributed to a group of people asking them how many times they had ordered takeout in the past week. They were also asked how much money they saved that week. The scatter plot displays the relationship between the data collected. the trend line goes through the points (1,230) and (3,190). What is the equation of the trend line. The equation should be in slope form. interpret the slope and y intercept in this context. predict the amount of money a person save when they order takeout 9 times.
Is it possible to determine the slope and y-intercept of the line just by referring to the given cost and shipping fee? How?
Do not put answers like k = 9 or k = -7. Your answer should be 9 or -7. %3D If you get an answer of All Real Numbers, type out All Real Numbers. If you get an answer of No Solution, type out No Solution. Question 1 Find the slope between (3, -2) and (-2, 3). Question 2
The scatter plot shows the average monthly temperature, x, and a family's monthly heating cost, y, for 25 different months. (a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit. (b) Using your equation from part (a), predict the monthly heating cost for a month with an average temperature of 25 °F.

The percent of defects is the x-coordinate, while the percent of new machines is the y-coordinate. So, the table of values corresponds to the points (25,32), (20,40), (15,50), (10,65), (5,70), (0,85). Question Using the linear relationship graphed above, estimate the percent of new machines if there is 12% defects in the shoes at various production facilities. Provide your answer below: _____
