1. 5.2 - slope Textbook pg. 294 Objective:
The student will find slope in order to recognize linear functions.

2. slope: constant rate of change. ∆y. rise/fall. ∆x
slope: constant rate of change ∆y rise/fall ∆x run linear function: has a slope, forms a nonvertical line
Decide if the function is linear. If so, state the slope.
X Y 2) X Y )

3. SLOPE FORMULA: y2 – y1 with points (x1, y1) & (x2, y2) x2 – x1
Find the slope from the points: 4) (4, -2) & (-1, 2)
5) (-2, -2) & (7, -2) 6) , 7 5 & 1 4 , 2 5

4. 4 Types of Slope Positive Negative Zero Undefined
