Answer:
A: -2
Step-by-step explanation:
Hopefully this helps!
In order to find the area of a rectangle, the formula is L*W (Length multiplied by Width). Our goal is to find these two measurements, so we will take the following steps:
1) Plot the coordinates on a graph (I have attached a visual guide)
2) Using the Pythagorean Theorem, or the Distance formula we can find the length and width:

3) We will use these values in the Area formula for a rectangle (L*W)
4) After solving the Area formula with the values retrieved from the Distance Formula we find that
the area is roughly 30 units squared.
Answer:
A
Step-by-step explanation:
Linear as said in it's name is a function that creates (visualy) a straight line.
FROM all the graphs A shows a straight line therefore, the answer.
