Answer: 1) B is correct, constant of variation is -2.
Step-by-step explanation:
1)
Direct variation states that a relationship between the two variables. we say y varies directly as x
i.e, or y =kx.................[1] ; where k is the constant of variation.
Given the equation:
Divide both sides by -4 we get;
Simplify:
.......[2]
On comparing equation [2] with [1] we get;
k = -2
Answer:

Step-by-step explanation:
First, expand the original equation:
(x + 1)(2x + 3)

Now simplify:

And that's your answer!
Answer:
Do y²-y¹/x²-x¹. So do 18-4/3-0 in order to get 14/3 and your slope intercept form! Hope this helped
