Graphing Systems of Inequalities

+Shading the solution Solving from Standard form into

Slope-Intercept Form What is your final answer? Graphing Systems of Equations Use Substitution to solve:

y-3 = x

4x + y = 8 Substitution Which method of solving systems of equations? and Why?

Graphing

Substitution

Elimination Solve for y 3x + 4y = -12 y= -3/4x - 3 3x + 4y = -12 -7x + 14y = 28 -7x + 14y = 28 y = 1/2x + 2 3x=8y - 2 3x=8y - 2 -8y = -3x - 2

y=3/8x + 2/8

y=3/8x + 1/4 Rate yourself from 1-5 on solving for y. 1- BAD

5-GREAT What is it called when there is one solution?

How does the graph look? Independent?

Dependent?

Inconsistent? What is it called when there is no solution? How does the graphs look like? Independent?

Dependent?

Inconsistent? Solve using Substitution y=4x -5

y=4x + 3 Elimination Create your own system of equations that would be easier to solve using Elimination Create your own

system of equations

that would be difficult

to solve using Elimination Solving Systems of Inequalities Create your own system of inequalities and solve by shading Rate yourself 1-5 on Systems of Inequalities Rate yourself 1 - 5 on Solving systems of equations by Graphing Rate yourself 1 - 5 on Solving systems of equations by Substitution Rate yourself 1 - 5 on Solving systems of equations by Elimination
