What is the difference between an equation and an inequality?
An equation has an equal sign and an inequality has an inequality symbol.
Look at how this student solved the equation below:
4d = 32
4 x 4d = 32 x 4
d = 128
Did they use the correct property of equality? Explain.
No they used multiplication. They should have used division because division is the inverse operation of multiplication.

r/25 = 5
r = 125
Is the following inequality graphed correctly? If not, what does the graph show?
