Question

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution.
2x − y = −5
4x − 2y = 10

Answer 1

so far i had -2x=2y=5 den4x-2y=10. i get -6=15...x is -2.5??

Answer 2

These are a pair of parallel lines. hence no point of intersection. Hence, no solution.

Answer 3

okay, so wat is the x and the y?

Answer 4

the lines never intersect. so are you asking what the y=mx+b equation is?

Answer 5

no, u hve to find the solution, if any
