Answer:
I dont understand the equation
Answer:
Two possible equations:

The system has 0 solution as parallel lines never cross each other.
Step-by-step explanation:
Considering the two lines are parallel, they both have the same slope.
let m be the slope of the two lines:

are the value on y axis where the two lines cross the axis.
Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.
To answer the question we start by placing two ordered pairs that satisfy the equation 
To do this we enter a value of "x" and then find "y"
Let's start with 


Then the first ordered pair that satisfies the equation is dot (2,4)
Now, for 

Then the second ordered pair that satisfies the equation is the point (0,0).
With these two pairs we draw the graph of the equation, which is shown in the attached image.
Answer:
D. 17/7
Step-by-step explanation:
Let's make 2 3/7 into an improper fraction. We first multiply the 2 to 7 and then add the 3. So 2 x 7 = 14, 14 + 3 = 17. The denominator always stays the same. Therefore our answer is 17/7
