A proportion looks like this:

It means that the quantity a,b,c and d are in the same proportion: the ratio between a and b is the same ratio between c and d.
They are particularly useful in situation when you have an example given, and you want to extrapolate the relationship for another couple.
For example, you can think of the following problem: "Five apples cost 2 dollars. How much will 8 apples cost?"
You can build the proportion

And then solve it for x:

The answer is 296 hope it helps
Answer:
There is no way to tell
Step-by-step explanation:
You could be way taller than your parents, the same height, or shorter. There are too many variables at play here.
Answer:
The point-slope form of the line is:

Hence, option B is correct.
Step-by-step explanation:
We know the point-slope form of the line equation is
where
- m is the slope of the line
Given
The slope m = 4
From the graph, we can take the point (-3, -4)
So, in our case:
(x₁, y₁) = (-3, -4)
m = 4
now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation



Therefore, the point-slope form of the line is:

Hence, option B is correct.
- The graph of the line is also attached.
We only need a calculator for this. But, to simplify and make sure you have a good experience here on Brainly, the answer is -0.15. All I did was find 12/80, and added the negative sign. If your issue was that you could not get the negative sign on your calculator, well, there is your answer
