M = (20 - 12)/(4 - 2)
= 8/2
= 4
slope = m = 4
Steps:
1. Draw a long box
2. Draw a horizontal line down the center of the box
3. Draw three equal sections in the top half ; shade in 1 segment
4. Draw 6 equal sections in the bottom half; shade in 2
You would do 4-2= 2 then 8/2 =4 .. final answer being 4
Mx = (Ax + Bx)/2 My = (Ay + By)
6 = (7 + Bx)/2 5 = (10 + By)/2
12 = 7 + Bx 10 = 10 + By
5 = Bx 0 = By
(5,0)
Answer:
intervals (-3,-1) and (0,+infinity)
Step-by-step explanation:
