They add up to 180 degrees.
5x+7+15x-7=180
20x=180
x=9
The line means it is -.3333333333333333 and so on , that's why it is greater than -.33
I would either graph these (which would be a easiest) then you would see a line that goes through (0, -2) on the y-axis
And you can either determine the slope from the graph or pick two points above and find the slope.
or spread them out evenly and fill out the missing pieces.
-8. -4
-4. -3
0
4. -1
6. -0.5
8
12. 1
Fill in the middle values and you can put (6,-0.5) on there
What pattern do u see? This way would be pretty hard.
Equation: y=(1/4)x-2
