Question

For the system of linear equations below, use graphing to determine in which quadrant the solution lies.

x+2y=-2
-2x+y=14

Answer 1

Quadrant I

Quadrant II

Quadrant III

Quadrant IV

Answer 2

solving simultaneously y=2 and x therefore equals -6. therefore the solution is in the top left quadrant. (since y is positive but x is negative).

solving t grapgically would just involve rearanging them both into the form y=mx +c and drwing them and seeing where they overlap.

that would give y=-x/2 -1 and y=2x+14
