Multiple Choice

When graphing an inequality what do we do when the equation is in slope intercept form?

• Change the equation to Y=Mx+b

• Solve it

• Replace the Y and X with 0 to see

Steps to graphing an inequality

• Eliminate similar terms

• Change equation to y=mx+b if its in slope intercept.

• Divide all #'s to get Y by its self

• Reverse the inequality if you multiply or divide by a negative.

• On the boundary line substitute its X and Y values into the original inequality.

• Get the 3 side notes(slope, y-intercept, dotted and shaded?)

• Graph the linear equation

Example #1:

What's all of the factors(side notes) for this graph?(4)
