No.
The relation is proportional when it can be written as
y = kx
As soon as you add a constant, you destroy the proportionality.
Answer:um
Step-by-step explanation:
A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).
In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.
The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”
Answer:
D
Step-by-step explanation.
The slope is the change in y over the change in x. If you look at the change in y, it goes from 2 to 3, and 3-2=1. If you look at the change in x, it goes from -1 to 3, and 3-(-1)=4 (if you subtract a negative it adds the number instead). IF you put the change in y over the change in x, you get 1/4, which is D
No, certain points on the plot line the share the same output
