2-1(intro) Slope Objectives: to find slope  NOTES Slope of a line is the ratio of rise to run for any two points on the line. The rise is the difference in the y-values of two points on a line. The run is the difference in the x-values of two points on a line.  What is the slope of this line? Identify 2 points that Hint? are exactly on the line. REMINDERS: *counting to the left or down is a negative * get in the habit of going UP or DOWN first, and then to the right. How can we find the slope if we don't have a graph? NOTES slope = rise = change in y = y run change in x x  Notes The Slope Formula When given two points (x1, y1) & (x2, y2) m = y2 - y1 x2 - x1 What is the slope of a line that passes through the points (4, 5) & (-2, -9)? (Use the slope formula) What is the slope of a line that passes through the points (-1, 0) & (3, -2)? 4 Types of Slope Special Slopes Special Slopes Special Slopes Slope is the steepness of the line. The greater the absolute value of a slope, the steeper the line. IXLs - K.1, K.2 Delta - Slope
