2-1 Slope – Sam practiced finding the slope from a pair of points. He labeled the first set of points as the coordinates (x1, y1) and the second set of points as (x2, y2). Then he practiced using the formula for the slope:
m = (y2 – y1) / (x2 – x2). Next he practiced finding the slope from the graph of a line. First he looked at the eight linear graphs and determined whether the graph of each line was positive or negative. Then he located two points on the line and labeled them as (x1, y1) and (x2, y2). Then he used the slope formula as he did before.
