Answer: 
Step-by-step explanation:
Step 1:-
Given equations are y=-2 x+30........(1)
another equation is y=4 x ..........(2)
Step 2:-
solving these two equations (1) and (2)
Equating both equations are 


Step 3:-
The final answer is 
Answer:
3rd one
Step-by-step explanation:
A.
the y intercept is where x=0
x represents the number of months
when the number of months is 0, that is the initial number of games won
that looks to be a little below y=2, so maybe y=1.8?
the y intercept is y≈1.8
it represents the number of games won with 0 months of practice
B.
we can use y=mx+b
m=slope
b=y intercept
we know the y intercept
find the slope
slope=rise/run
the I'm going from x=0 to x=10
the rise is about 18.95 (from 1.8 to 20.75)
the run is 10
so slope would be 18.95/10=1.895
the equation would be y=1.895x+1.8
the points were (0,1.8) and (10,20.75)
