Explain the steps you take to graph an inequality.

Let's say you had something in the form Ax+By > C

Solving for y would get it into the form y > mx+b only if B is positive.

If B were negative, then the sign would flip and you'd have y < mx+b

For y > mx+b, you shade above the boundary line and y < mx+b has you shade below the boundary line.

The boundary line itself is y = mx+b which goes through two points. Use a solid line if there is an "or equal to" as part of the inequality sign. Otherwise, use a dashed boundary line.

Examples:

An online grapher such as desmos will quickly let you graph any inequality so you can check your work.

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
