Q:
# Choose the system of inequalities whose solution is represented by the graph.

Accepted Solution

A:

Answer: -x + y > -4; x + y < 3 . . . . . last choiceStep-by-step explanation:The boundary lines are both dashed, so there will be no "or equal to" as part of the inequality symbols (eliminates the second choice).The downward sloping line has x- and y-intercepts that are both 3, so it will have the equation in intercept form ... x/3 + y/3 = 1Multiplying by 3 gives x+y=3. The shading is below it, so the inequality with that line as the boundary is ... x + y < 3This inequality is only part of the last choice.__The upward sloping line has x- and y- intercepts of 4 and -4, so its equation in intercept form is ... x/4 + y/-4 = 1Multiplying by -4 gives -x+y=-4. The shading is above it, so the inequality with that boundary line is ... -x + y > -4This inequality is included in the last choice.
