Lesson #5 Inequalities and Systems of Inequalities

• graph the equality equation on desmos

• add a table by clicking the + in the left side corner and table, and put the pairs in

• edit the points display by looking at the ranges of the x and y values on the graph

• graph the points and guess and check the answer

Examples

• For which of the following tables are all the values of x and their corresponding values or y solutions to the given inequality y < 6x+2

  • the answer is the table that is in the shaded region

• y>14 and 4x+y<18 The point (x,53) is a solution to the system of inequalities in the xy plane. Which of the following could be the value of x?

  • the solutions to the systems on the graph is the region that is shaded by both the red and the blue colors

  • type the 2 equations in

  • type (x,53) on the next line, x being each answer choice
