Great practice on using scatterplots and making the connection to fit of a linear function. One common strategy is to draw the line and estimate the profit at 18 months, then find the equation with the calculator and compare the two results. The slope is negative c. The slope is zero d. The slope is undefined 2. So we discuss the relationship between distance from the beach and price and discuss how they can sort through all the distractors (we call all the extra fluff "garbage."). Weight expected? For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line. It can be used to estimate data on a graph. The second major misconception in this question is that students don't understand the typical procedure for acceptable rounding. Save.
