Answer:
-4
Step-by-step explanation:
In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).
Here, the coefficient of x is -4.
The slope is -4.
_____
<em>Additional comment</em>
Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...
y = kx . . . . . with no added constant
"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):
y = mx + b
Hello from MrBillDoesMath!
Answer:
+2
Discussion:
-8 (17 - 12) / ( -2 (8 - (-2)) ) -
= -8 ( 5) / ( -2 ( 8+2)) as 17 -12 = 5 and -(-2) = +2
= -40/ ( -2 (10))
= -40/(-20) =
= +2
which is the third choice.
Thank you,
MrB
