If the slope is positive then the absolute value will look like what?
A V.
Solve by graphing.
|x + 2| = 3
x = -5, 1
graph is on google doc. #5
Solve for x.
|2x + 3| = 5
x = -1, 4
Which is slope-intercept form?
a. Ax^2+Bx+C = y
b. y = mx+b
c. f(x) = a|x-h|+k
What is b.
Graph: f(x) = 2|x| - 1
I will check your board for the answer.

f(x) = |x - 2|
Solve by graphing.
|2x - 8| = 4
x = 2, 6
Answer on google doc. #6
Solve for x.
|x - 2| + 6 = 10
x = 6, -2
Who is Ms. Paye's favorite author?

c. Stephen King
What is c.
Graph: f(x) = |x + 5| - 3
I will check your board for the answer.
Slope: 1
Vertex: (-5,-3)
Write the function.
#2 on google doc.
f(x) = 3|x - 2| + 3
Solve by graphing.
2 |x - 1| - 3 = 5
x = 5, -3
Graph is on google doc. #7
Solve for x.
3 |x + 2| - 7 = 14
x = 5, -9
Identify what the a, h, and k values do in the equation.
f(x) = -3|x + 2| - 5
a = -3 and it is the slope
h = -2 and it shifts the graph 2 to the left
k = -5 and it shifts the graph 5 down
Graph: f(x) = -1/3 |x + 1| - 2
Vertex: (-1,-2)
Write the equation from the graph.
#3 on the google doc.
f(x) = -1 |x + 1| + 3
Solve by graphing.
|x + 7| + 5 = 4
x = no solutions
graph is on google doc. #8
Solve for x.
-2 |2x + 3| + 14 = -16
x = -9, 6
