Since x=-10, plug that into the equation.
f(x) = 2(-10) + 11
= -20 + 11
y = -9
So the ordered pair in (x,y) terms is (-10,-9).
Answer:

Step-by-step explanation:
A 188 inches .2 Because you have to run them all to the nearest five
From one vertex of an octagon you can draw 5 diagonals.
There are 8 vertices in an octagon, and we are choosing one as our starting vertex. There are then 7 vertices left to draw a line to, but 2 of the vertices are already connected to our main vertex (because they are connected along the side of the octagon). That leaves 5 vertices to draw a diagonal to from our original vertex.
Your answer will be 12 since 8/8 is one whole and you need 12 so your answer is 12
