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.

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.
Hello!
I believe the answers are:
A) The vertex is (1, −6)
C) The graph has a minimum.
I hope it helps!
19 is you awnser since:
By order of operations first do the exponent and then do the multiplication and finally the subtraction
3 to the third is 27
4 times 2 is 8
so 27-8 is 19
3 to the(3)-(4)(2)
27-(4)(2)
27-8
19 is your answer
