Warm-up 1.Write the equation of the line that passes through the point (0,5) and has a slope of 4. 2.Find the slope of a line passing through (-3,6) and (4, 8). 3.If y varies directly with x and x=7 when y=21, find y when x=2.

2
Section 2-5: Absolute Value Functions and Graphs Goal 2.08: Use equations and inequalities with absolute value to model and solve problems; justify results: a) Solve using tables, graphs, and algebraic properties.

3
y = |m x + b| + c, Vertex is the point where the function reaches its maximum or minimum, located at (-b/m, c)

4
Example y = |3x + 12| (-12/3, 0) = (-4, 0)

5
Example y = |2x + 5| - 2
