Question

The graph of a system of two linear equations has no solution. What is true about the lines?

Answer 1

two lines r parallel

Answer 2

They are parallel.

2 lines in 2 dimensions must either intersect or are parallel. If they intersect there is 1 unique solution. If they are parallel, there is either infinitely many solutions (they are the same line) or 0 solutions (they are different parallel lines)

Answer 3

right.

Answer 4

but then it also asked. Which number of solutions is not possible for a system of two linear equations?
A.2
B.1
C.0
D.infinite

Answer 5

two line can intersect only one

Answer 6

Or infinitely many or 0. only impossible number of solutions in euclidean geometry is 2 (out of those choices).

Answer 7

bt if two lines r parallel to each othet then no solution occurs

Answer 8

so the answer is B? if so, explain method

Answer 9

2 solution is impossible

Answer 10

The answer would be A) 2. You can have two lines that are parallel or intersect once. Lines will never intersect twice

Answer 11

could you help me with Solve the system by substitution.

y = 2x
3x + 2y = 21
A.x = 3, y = 6
B.x = 6, y = 3
C.x = 3, y = –6
D.x = –6, y = 3
