Explain why graphing the solutions of an inequality is more efficient than listing all the solutions of the inequality.

The saying "A picture is worth a thousand words" comes to mind here. You can list all of the possible points in a solution region, or you can list a few points to give the general pattern. Though this method requires a bit more work than simply graphing and showing the solution shaded region. A visual is often more efficient at conveying a message especially to those who aren't proficient with algebra. I'm sure there are other reasons why graphs are the better choice, but that's all I could think of really.

The number of solutions to an inequality is infinite. You couldn't possibly list them. That's why a graph or set notation has to be used.

examples:

x ≥ 5
The solution set is [5, infinity) in set notation or a graph showing the shaded area above x = 5

two variable ...

y > 2x+1
solution set must be graphed because it's every point above the line y = 2x+1 all the way to infinity.

you can't possibly list all the solutions. Not even for a system of inequalities where the solution set is defined by boundaries can you list all the solutions because there are still an infinite number of points within the bounds.

The two lines graphed below are not parallel.How many solutions are there to system of equations
nika2105 [10]

we need the graph/ lines,

but just remember

wherever 2 lines intersect, that is a solution

if they are paralell, no solutions

if they cross, 1 solution

if they are the same line/ the lines are on top of each other exactly, infinite solutions
