Answer: = 8
Step-by-step explanation: Hope this help :D
The y intercept is -2, but I don't remember how to find the vertex sorry
F (x)=y
y=2x-9
X Y
-2 -15 y=2 (-2)-9
y=-4+-9
y=-15
-1 -11 y=2 (-1)-9
y=-2+-9
y=-11
0 -9 y=2 (0)-9
y=0+-9
y=-9
1 -7 y=2 (1)-9
y=2+-9
y=-1
2 -5 y=2 (2)-9
y=4+-9
y=-5
Here is all the work
Answer:
The measure of one angle is
, and the measure of the other one is 
Step-by-step explanation:
Recall that supplementary angles are those whose addition renders 
We need to find the measure of two such angles whose difference is precisely
.
Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":
