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