Alright, so for AB and CD to be parallel, CX and DX would have to be equal, as is with AX and BX. In addition, for CD and AB to be parallel, all sides in both triangles are either equal or not all sides in even one triangle are equal. Therefore, CD is not 3. In addition, two sides of a triangle combined must be greater than the third, so that leaves 5, 4, and 2 for CD. If it was 5, that would mean that all sides are equal, so that leaves 4 and 2. However, I don't see anything to prove either one right, sorry:/

using line and triangle property you can solve this question
Answer:
Plot a point at (0,-3) and (2,-2) then connect.
Step-by-step explanation:
Use y=mx +b to guide where you graph the line. b is the y -intercept and shoud be graphed on the y-axis. m represents the slope which is rise/run. To graph the line, mark -3 on the y-intercept. Then plot the next point 1 unit up and 2 units over at (2, -2).
Answer:
Both
and
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug
into 

The solution verifies the equation.
Step 2: Plug
into 

The solution verifies both equations. Therefore,
is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug
into 

Step 4: Plug
into 

The solution verifies both equations. Therefore,
is another solution to this system.
