Chapter 5 Linear Inequality Exam Review

Which of the following inequalities matches the given graph?

• y ≥ 2/5x + 1

• y ≥ -2/5x + 1

• y≤ 2/5x + 1

• y ≥ -2/5x - 1

Consider the equation:

y= 1x+4

Identify the slope and y-intercept.

• m=4, b=-x

• m=-x, b=4

• m=1, b=4

• m=-1, b=4

How can I tell if an inequality will have a solid line?

• It has an equal sign.
• The symbol is greater than.
• The symbol has "or equal to."
• You just guess.
