Answer:
B)
and C) 
Step-by-step explanation:
Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.
Considering 
has a constant positive rate of slope 2.

has a constant negative rate of slope -7

Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
Answer:
the midpoint would be (5,9)
Answer:
x = 136°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, that is
x + 44° = 180° (subtract 44° from both sides )
x = 136°
Answer:
You could try to do it side by side then the area x side.
