Answer:
The 3rd graph represents the point (-1, 4) as the solution to the system of linear equations.
The correct graph is also attached below.
Step-by-step explanation:
We know when two lines meet at a certain point, the point where they meet is called the point of intersection.
We also know that the point of intersection of two lines is termed as the solution of the system of linear equations.
We are given the point (-1, 4) as the solution of the system of linear equations.
It means the two lines meet at x = -1, and y = 4.
In other words,
(x, y) = (-1, 4) is called the point of intersection of the system of linear equations.
Now, if we closely check the graph of these two lines, we can easily figure out that the 3rd from the right side is the graph that represents the solution to the system of linear equations.
The 3rd graph indicates that the two lines meet at x = -1, and y = 4.
Hence, the point of intersection of 3rd graph is:
(x, y) = (-1, 4)
Therefore, the 3rd graph represents the point (-1, 4) as the solution to the system of linear equations.
The correct graph is also attached below.
Area: 35 inches
Perimeter: 24
Here's how I got my answer:
<u>Area:</u> The formula for the area of a rectangle is . So if we plug that in, it would be
, which is 35.
<u>Perimeter:</u> You can get the perimeter by adding all the sides together, which is , which is 24.
