Estimate the solution to the system of these linear equations based on the graph. y=−x+6 y=3x−2 (1 point)
Based on the graph, the estimated solution to this system of linear equations is (2, 4).
Determine the number of solutions to this system of linear equations: 2x+y=6 4x+2y=8 (1 point) Responses infinite infinite 0 0 1 1 2
The system of equations 2x + y = 6 and 4x + 2y = 8 are equivalent because the second equation is just the first equation multiplied by 2. Therefore, they represent the same line. As a result, there are infinitely many solutions to this system of equations.
Solve the system of equations. 4x−8y=−36 −6x+y=32 (1 point) (, )
To solve this system of equations:
4x - 8y = -36
-6x + y = 32
We can use the elimination method by multiplying the second equation by 8 to match the coefficients of y with the first equation:
-6x + y = 32 *8 -> -48x + 8y = 256
Now, the system becomes:
4x - 8y = -36
-48x + 8y = 256
Now, adding these two equations, we get:
-44x = 220
x = -220 / -44
x = 5
Now, substitute the value of x back into one of the original equations, let's use the first equation:
4(5) - 8y = -36
20 - 8y = -36
-8y = -36 - 20
-8y = -56
y = -56 / -8
y = 7
Therefore, the solution to the system of equations is (5, 7).
4x - 8y = -36
-6x + y = 32
We can use the elimination method by multiplying the second equation by 8 to match the coefficients of y with the first equation:
-6x + y = 32 *8 -> -48x + 8y = 256
Now, the system becomes:
4x - 8y = -36
-48x + 8y = 256
Now, adding these two equations, we get:
-44x = 220
x = -220 / -44
x = 5
Now, substitute the value of x back into one of the original equations, let's use the first equation:
4(5) - 8y = -36
20 - 8y = -36
-8y = -36 - 20
-8y = -56
y = -56 / -8
y = 7
Therefore, the solution to the system of equations is (5, 7).
Solve the system of equations. 6x−3y=−6 9x−3y=−18 (1 point) (, )
To solve the system of equations:
6x - 3y = -6
9x - 3y = -18
We can see that the two equations are essentially the same with different constants. Therefore, there is no consistent solution that satisfies both equations simultaneously.
Hence, the system of equations is inconsistent and has no solution.

9x - 3y = -18

Apologies for the confusion in the previous response.
Let's reevaluate the system of equations:
6x - 3y = -6
9x - 3y = -18
To solve this system, we can notice that the two equations both have the same coefficient when the terms are aligned. This tells us that the two equations are dependent on each other, meaning that they represent the same line.
Therefore, the system is consistent and dependent, leading to an infinite number of solutions. The solution set can be expressed as (x, y) = (t, 2t), where t is a real number representing the parameter for the solutions.
