These are the statements that accompany this question:
<span>A.The function is a linear function.
B.The function is a nonlinear function.
C.The function does not change at a constant rate.
D.The function is an increasing function.
E.The function changes at a constant rate.
An this is the assesment of each of statement:
</span>
<span>A.The function is a linear function.
TRUE: a linear function can take the forms Ax + By - C = 0, or y = mb + b
You can verify that y = 2000 - 90 x is of this type.
B.The function is a nonlinear function.
FALSE: we showed the opposite in A)
C.The function does not change at a constant rate.
FALSE: the rate of change of a linear function is constant and it is known as the slope.
D.The function is an increasing function.
FALSE: the value of y decreases as x increases, given that the slope is negative ( -90).
E.The function changes at a constant rate.
TRUE: the constant rate is the slope, i.e. - 90.

I would think (10,1) and (1,9) would make the most accurate line of best fit since it is surrounded by most points. Would you agree? Since the (10,0) may just be an anomaly plot.
Hello from MrBillDoesMath!
Answer:
Rule: Y = 5x - 3
Table Line 4: Y (output) = 37
Table Line 5: X (input) = 10
Discussion:
This one had MrBill going for a while! The rule appears to be
Y = 5 * x - 3
Check it out! Substitute some table values (input) and check the (output) values.
Table line 4: Y(8) = 5 * 8 - 3 = 40 - 3 = 37 (Output)
Table line 5: If Y = 47 = 5*x -3 => add 3 to both sides
47 + 3= 5x => as 47 +3 = 50
50 = 5x => divide both sides by 5
x = 50/5 = 10 (input)
Thank you,
MrB
Answer:
Step-by-step explanation:
(-2, -3) (-1, -1)
(-1 + 3)/(-1 + 2)= 2/1 = 2
y + 3 = 2(x + 2)
y + 3= 2x + 4
y = 2x + 1
Answer:
-3+(-6)+4=-5
Step-by-step explanation:
-3 drops 6 degrees,now -9 degrees then it rises 4 degrees which makes it now -5 degrees.
