Answer:
Slopes
Line 1 = 1
Line 2 = -2
Explanation:
See the attached worksheet. Slope is defined as the "Rise/Run" of a line. Rise is the change in y and Run is the change in x that led to the change in y. Identify any two points on a straight line and the slope may be calculated, as shown on the worksheet. Set up an Excel table, enter the x and y values of the two selected points for each line, then Find the Rise with (y2 - y1) and the Run from (x2-x1).
