1.5.2. Solving linear and quadratic inequalities algebraically and graphically

1.5.2.1. Step 1 Write down your inequality.

1.5.2.2. Step 2 Solve your inequality for x or y. You can solve for either as long as you are consistent. Normally, you solve for x.

1.5.2.3. Step 3 Create a table of values for y. Normally, you will choose three values. Three points are all that is needed for straight lines. You can choose any three values you wish. If your inequality solved with fractions, you may want to choose values divisible by the denominator or anything to turn the fraction into a whole number. Zero is also a good choice for a value.

If the point makes your inequality true, then shade that side of the line. If the point makes your inequality false, then shade the opposite side of the line.
