Quarter 2: Weekland 2 MELCS: Differentiate linear inequalities in two variables from linear equations in two variables.
illustrates and graphs linear Inequalities in two variables.
Solves problems involving linear inequalities in two variables.
Activity 1. EXPRESS YOURSELFI
Direction: Shown below are two sets of mathematical statements. Use these to answer the questions
that follow.
Y=2x + 1
Y> 2x + 1
3x + 4y = 15
10-5y = 7x
3x + 4y < 15
10 - 5y 27x
Y=6x 12
9y-8=4x
Y S 6x +12
9y-8<4x
Questions:
1. How do you describe the mathematical statements in each set?
2. What do you call the left member and the right member of each mathematical statement?
3. How do you differentiate 2x + 1 from y = 2x + 1? How about 9y 8 and 9y - 8 = 4x?
4. How would you differentiate mathematical expressions from mathematical equations?
5. Give at least three examples of mathematical expressions and mathematical equations.
6. Compare the two sets of mathematical statements. What statements can you make?
7. Which of the given sets is the set of mathematical equations? How about the set of inequalities?
&. How do you differentiate mathematical equations from inequalities?
9. Give at least three examples of mathematical equations and inequalities.
Were you able to differentiate between mathematical expressions and mathematical
