Question

Which system has no solutions?
Which system has infinite solutions?
Which system has (1, 3) as the solution?
Which system has (-8, 0) as the solution?
Which system has (-2, -2) as the solution?

Answer 1

4x+6y=-12 2x+3y=9
x-y=-2 3x-y=0

Answer 2

A system with infinite solutions are the same line.
For a point (x,y) to be a solution, substituted the x and y into the eqation.
A system with no solutions are parallel.

Answer 3

x+y=-4 -3x+2y=2
x+4=-1 4x+4y=-4

Answer 4

x-4y=-8 2x-3y=-16

Answer 5

help please will fan and medal

Answer 6

4x+6y=-12 2x+3y=9
x-y=-2 3x-y=0
x+y=-4 -3x+2y=2
x+4=-1 4x+4y=
-4x-4y=-8 2x-3y=-16

Answer 7

for a solution of (1,3)
you can graph any 2 lines that intersect at (1,3) and write down the equations for the 2 lines as the system
use this process for the next 2
