The third graphic system shares the same set of solutions.
Notice that the first graph is two parallel lines that never cut.
The second graph has two lines that intersect at a point. Therefore, compare a single solution.
The third graph shares the whole set of solutions since, for each x, both lines take the same Y value
answer
Third graphic.
The answer is A, I figured this out by process of elimination.
Answer:
1. The graph is non-proportional because it starts from (0, 2).
2. The slope of the line is 3.
3. y=3x+2
Step-by-step explanation:
The graph is non-proportional since it didn't start from the origin (0, 0). If the graph starts from the origin, then it's proportional.
To find the slope of the line, use this equation, 
or 
to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.
I chose (0, 2) and (1, 5) to find the slope
Once you find the slope, write the equation in y=mx+b form to find what b is with one of the points given.
----------------------
2 = b
Equation of the line: y=3x+2
Equation B is linear. A linear equation will not contain exponents.
The correct answer is D because you would multiply the numbers in the bracket by 6 which would equal to 30
