Exploring Systems of Inequalities

Why is it important to rearrange an inequality to the form y = mx + b before graphing?

• It allows for easier identification of the slope and y-intercept.

• It makes it easier to find the x-intercept.

• It simplifies the inequality.

• It helps in solving the inequality algebraically.
