### Lesson slope power point

1. 1. Lesson: SlopeCourtesy of BSN
2. 2. Slope – the ratio of the vertical change (rise) to the horizontal change(run) between any two points. rise change in y slope run change in x • y2 y1 (x2, y2) m x2 x1 • (x1, y1)
3. 3. EX Find the slope of the line. (x1, y1) (x2, y2) (-3, 2) (4, 3) (4, 3) (-3, 2) y2 y1 m x2 x1 3 2 m 4 ( 3) 1 m 7
4. 4. EX Find the slope of the line that passes through (3, 5) and ( 6, -1). (x1, y1) (x2, y2) (3, 5) (6, -1) y2 y1 m x2 x1 1 5 m 6 3 6 m 2 3
5. 5. EX Find the slope of the line that passes through (-2, 4) and ( 4, 4). (x1, y1) (x2, y2) (-2, 4) (4, 4) y2 y1 m x2 x1 4 4 m 4 ( 2) 0 m 0 6
