Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
Answer:
A: Yes, the relationship is linear.
Step-by-step explanation:
1=60, so we can assume that 3=180 because 60x3=180. we can use this strategy for the rest of the data and confirm that the line has a consistent slope of 60/1.
3 1/3 x 5 2/4 = 18 1/3 so 5 2/4 is your answer
Okay what you could do is type 400 divided by 2/3 into a calculator, but on paper you would do 400 divided by 3, which is 150, then multiply 150 by 2 since it’s “2/3’s” of 400.
400 / 3 = 150,
150 x 2 = 300, so 300 is correct.
48miles/hour means divide by 60 to get miles/minute (since there are 60 minutes in an hour).
So yes .8 miles/minute
After two minutes would be 1.6 miles
Perfect.
