Answer:
C
Step-by-step explanation:
y=mx+b, where x any are variables, m is the slope and b is the y-int.
Step 1: Find the y-int
y-int = 3.25 (13/4)
Step 2: Find the slope using RISE/RUN
-13/7
Answer is C
Hope that helps

B. 2 2:3=30:45 30/45 can be simplified to 2/3
Answer:



Step-by-step explanation:
The equation of a parabola in the form of the vertex is the following:

and the vertex will be in the coordinates: 
for a. 
we can see that
, and 
so the vertex is at 
for b. 
we can re accommodate this equation as: 
in this form is easier to see that
, and 
so the vertex is at 
for c. 
we can re accommodate this equation as: 
and as we can see
and 
so the vertex is at
