Step 1
The slope (m) is given by the formula: m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are the coordinates of two points on the line. In this case, we have the points (20,30) and (70,60). So, we can substitute these values into the formula: m = (60 - 30) Show more…

Draw a scatter diagram for each given data set. Use graph paper. From your graph determine whether there is a linear relationship between the variables. $$\begin{array}{|c|c|}\hline & \text { Grade } \\\text { ACT } & \text { Point } \\\text { Score } & \text { Average } \\\hline 18 & 2.2 \\26 & 3.4 \\20 & 2.8 \\17 & 2.0 \\19 & 2.6 \\23 & 3.2 \\25 & 3.6 \\30 & 4.0\\\hline\end{array}$$
