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.

Answer:
The length of the mat is 60 in.
Step-by-step explanation:
Given :
Mats are inclined to form a triangle.
two sides of the mat are right triangles.
Hence the triangle formed is right angled triangle.
Let the length be x.
Now,The height of the mat is 28 inches shorter than the length of the mat.
Height of mat = x - 28
Also, the hypotenuse is 8 inches longer than the length of the mat.
Hypotenuse = x + 8
Hence by using Pythagoras theorem we get ,
Now we get 2 values of length 12 and 60.
But height is 28 in less than length.
And when we take length value as 12 the height will be negative hence it can't be true.
Hence the Length of mat = 60 in.
