This week we learned how to graph inequalities with two variables. These inequalities are essentially forms of the equation y=mx+b, used to graph lines. The same idea can be applied to graphing the inequalities.
However depending on the inequality the line will either be broken or solid.
solid line = or
broken line = or
using the same idea as y=mx+b, we can find the slope, and the y-intercept.
“m” represents our slope, if it’s a whole number it can be read as with “n” being your rise(y), and 1 being your run(x).
For instance: If you were to graph , your y-intercept would be 2, and your slope would be
It would look like this:
The area shaded, is figured out by testing x and y coordinates in your equation, until the equation is made true through the coordinates chosen.
