Bell Work 12/2/14 Graph the equation.
Yesterday’s Homework • Any questions? • Please pass your homework to the front. • Make sure the correct heading is on your paper. • Is your NAME on your paper? • Make sure the homework is 100% complete. • Incomplete work will NOT be accepted.
Heading 1/8/2020 Slope (using a graph) TSWBAT: find the slope of a line using a graph. Students understand the concepts of parallel lines and perpendicular lines and how those slopes are related. Students are able to find the equation of a line perpendicular to a given line that passes through a given point.
Notes • Slope (m) = Ratio of the vertical rise to the horizontal run. • Tells you how the line MOVES. • Our definition • Formula Other formulas used.
Notes • Types of Slope a. POSITIVE b. NEGATIVE RISES from left to right. FALLS from left to right. c. ZERO d. UNDEFINED No rise (horizontal). No run (vertical).
Notes • Rules to finding Slope 1. Identify points on the line. 2. Pick the point on the left. • Go up/down first. • Go right/left next. 3.
Notes Now you try. Find the slope. 1. Identify points on the line. 2. Pick the point on the left. • Go up/down first. • Go right/left next. 3.

Class Work Find the slope.
Summary • The slope is how the line ______. To find it using a graph just pick two points and use the definition of rise/____. Pick the point on the left and move up (positive) or down (________) until you are level with the other point. Now go right until you hit the point. Reduce if ________. • moves • run • negative • possible
