Question

Just 4 math questions...The first graph is for 1, the second graph is for 2, and the third graph is for 3. Thanks for the help!

1.
For the graph shown, select the statement that best represents the given system of equations.

6x + 4y = 2
3x + 2y = 1

A.
consistent and independent

B.
coincident

C.
inconsistent

D.
not enough information

2.
For the graph shown, select the statement that best represents the given system of equations.

4y + x = 2
8y + 2x = 4



A.
coincident

B.
consistent and independent

C.
inconsistent

D.
not enough information


3.
How many solutions does this system of equations have?



A.
none

B.
exactly one

C.
exactly two

D.
infinitely many



4.
The system of equations is coincident.

What are the missing values?

x + 3y = 5
4x + ___ y = ___

Answer 1

1.    the two lines are coincident.  as the second equation is obtained by multiplying first equation by 2.

2.  the two given lines are coincident.

3.  infinitely many , as every point on the line is a solution of the system of equations.

4.  missing are :    3 * 4  and  5 * 4
