How do I graph an inequality in one variable?

1 answer:

7 0

It depends on the variable.

If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).

Similarly for y, except it would be a horizontal line with either everything above or below shaded.

You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded

Try plugging them in, might seem tedious, but it's the best way to practice. if you plug in a pair and the left side of the equation is less than or equal to 6, it's the right answer.

Answer:

$\frac{x + x + x + x + x + x + x}{7} = 6 \\ \frac{7x}{7} = 6 \\ x = 6 \\ \frac{6 + 10}{8} = \frac{16}{2}$
