Answer:
-9/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-12)/(0-(-2))
m=-9/(0+2)
m=-9/2
-36 degrees = 0.62831853 radians
Answer:

Step-by-step explanation:
First, find 2 points on the graph where the line intersects.
For this example, let's use (2, -1) and (4, -4). Find the slope using the rise over run equation. See below:

Answer:
b
Step-by-step explanation:
p=2w+2l
80 =2w+32
subtract 32 from each side
48=2w
divide each by 2
Your answer would be (D).
Explanation: Rotated perpendicular lines always remain perpendicular lines.
Rotation is a rigid transformation, so the lines remain perpendicular.
