SYSTEMS OF LINEAR EQUATIONS

AND INEQUALITIES

Week 01: Review on Graphing Linear Equations Prepared by: Jojo M. Lucion

Let's Practice for Mastery 1

A. Transform the following equations to y-form.

1. x + y = 8

2. x - y = - 4

3. x + y = 2 4. 2x - y = 8

5. 3x + 2y = 5

6. 2x + 3y = 0

7. 3x + y = 5

8. 5x - y = 3

9.2x + 3y = 12

10. 4x -3y = 6

B. Identify the slope (m) and the y-intercept (b) in A.

Let's Check your Understanding 1

Identify the slope and the y-intercept

1. y = -x + 3

2. y = -3x + 12

3. y = - 3 x+ 2 2

4. -3x - 5y = 1

5 x - 2y= 1

Let's Practice for Mastery 2

Graph the following linear equations using the slope- intercept method.

1. x-y=8 4. 3x + 2y = 4

2. -3x + 4y = 12

5. -x - 2y = -8

3. 2x - 3y = 6

Let's Check Your Understanding 2 Graph the following linear equations using the slope- intercept method.

1. x + y = 3

2. 2. 5x -y = 3

3. -x + y = 4

4. 2x + y = 3

5. 5. -4x + y = - 6

Let's Do It. Treasure Hunt With Slopes

Using the definition of slope, draw lines with the slopes listed below. A correct solution will

trace the route to the treasure.

1. 3 2. 1/4 3. - 2 /5 4. 0 5. 1 6. -1

7. no slope 8. 2/7 9. 3/2 10. 1/3 11. – 3/4 12. 3
