Find the y-intercept using the Slope-Intercept Formula at (0, 64) Given scatterplots that represent problem situations, the student will determine if the data has strong vs weak correlation as well as … The mean, median, and mode are 3 measures of the center or central tendency of a set of data. Answer: graph. Explanation: Find the slope using the Slope Formula 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. Data have a negative association if the points get lower from left to right. Example 12. _____________.
