Answer:
Answer is: A(Linear)
Step-by-step explanation:
A linear function is a function whose graph is a straight line.
It is given that Mary plotted a graph and she found out that the difference in the y values is the same. So such a thing could happen when a function is a linear function.
since, a linear equation is given as:
where a and b are real numbers.
so for distinct values of x say 
we get the y-values as 
now,
so for equally spaced 
we get the difference in y-value to be equal.
Hence, the function is Linear.

Answer:
working together, they can paint the room in 4 hrs 14 min
Step-by-step explanation:
Multiply both sides by 72x
8x+%2B+9x+=+72
17x+=+72
x+=+4.24 hrs
.24%2A60+=+14.4
working together, they can paint the room in 4 hrs 14 min
Answer: the answer is 2
Step-by-step explanation:
First, let's put that line in standard form
y - 3 = 3(x + 1)
y - 3 = 3x + 3
y = 3x + 6
(Standard form is y = mx+b, where m is slope and b is y-intercept.)
Now, a line parallel to that line would have the same slope of 3. So now we have m = 3. Plug that in for m and now we have
y = 3x + b
But we still need the b value. We can get that by plugging in the point (0, -3)
(-3) = 3(0) + b
-3 = 0 + b
b = -3
Now put b back into the equation and your final equation is
y = 3x - 3
