3.3 Solving Systems of Inequalities

• (9-17) all


• if an inequality is in y = mx + b form, then start by graphing the y-intercept (on the y-axis) and then using the slope to find your second point.


• if an inequality is in Standard form, then find the x-intercept by substituting y with zero. then find the y-intercept by substituting x with zero. if you need to use the slope, remember that that is equal to -(A/B)

3.5 Solving 3 Variable Systems #2

• bc of FCAT Writing today, I did not get to teach a new lesson so now you will be practicing this concept again by doing the even problems....and yes, i will be checking tomorrow so make sure you have it done!

3.1 Solving systems by Graphing (even)

• due to the scheduling presentation, i am assigning the even problems from last night's HW


• also, i forgot to go over the other aim in class today. please add the following to your notes (yes, i will be checking your notse tomorrow!)


• Aim 4: to classify a system WITHOUT graphing


• underneath this aim, copy the take note chart on pg 149


• then copy the box beneath that one labelled Problem 4. basically, copy EVERYTHING on pg 149


• (8-14) even


• (19-33) all


• make sure you CHECK your answers in the back of the book for the odd problems!

Writing Equations in all 3 forms and Graphing

write an equation in a) point-slope form, b) slope-intercept form and c) standard form if the line contains:

1. (- 3, 5) and (7, 4)


2. (2, 6) and ( - 8, 10)


3. (- 3, -4) and (1, 5)


4. (10, 12) and (3, 6)


5. (- 8 , -12) and (- 3, 2)


6. graph: y - 4 = 2/3 (x + 1)


7. graph: y + 2 = -1/4 (x - 5)


8. graph: y = 3/4 x + 2


9. graph: y = 3


10. graph: x = -1


11. graph: 2x + 4y = -8


12. graph: 3x - 6y =6


13. graph: 4x - 5y =10

Standard Form & Graphing

Write the equation of a line in:

a) point-slope form; (when doing this form, please use the FIRST given point!)

b) slope-intercept form and

c) standard form

(YES, i want you to write out ALL 3 forms!) if it contains:

1. (-3,-4) and (7,12)



2. (-5, 2) and (-8, 10)



3. (8, -9) and (1,-3)



4. (-3,-8) and (-9,-2)



5. (11, 6) and (-2, 1)

Graph the following equations: (if you don't have graph paper, you can download some from the Home page of my website). Make sure you LABEL your points!

6. y-5=2/5 (x+3)

7. y+2 = -3/2 (x-4)

8. y=5/3x -5

9. y = -3/7 x + 4

10. y = x + 1

11. y = x

12. x = 3

13. y = -2

14. 3x - 2y = 6

15. 10x + 5y =10

16. 4x + 3y = -8 (hint hint: one of the intercepts is ugly so you will have to find the slope and use the slope to graph the second point)

17. 2x - 5y = 15 (hint hint: one of the intercepts is ugly so you will have to find the slope and use the slope to graph the second point)

Equations of Lines

Write the equation of a line in a) slope-intercept form and b) in standard form if the line contains:

1. (-3,4) and (6, -8)


2. (9,-1) and (12,-4)

2.3 Slope-Interecept Form

Write the equation of a line in Slope-Intercept Form if given the following information.

1. m = 3/4 (5, 7)




2. m = - 2/3 (- 10, 4)




3. m = 7/5 ( - 2, 6)




4. m = 5/6 (- 10, 11)

8. (15, - 12) (2, - 5)




9. (- 3, - 4) (- 15, 6)




10. (2, 7) (- 8, 3)

how to write the equation of a line in slope-intercept form:

1. write point-slope form: y-y1 = m(x-x1)

2. substitute x1 and y1 with a point on the line.

3. substitute m (you might have to caluculate it yourself. if you do, use the slope formula from aim 1)

4. write out slope-intercept form (y = mx + b)

5. solve for y.

Virtual Counselor Printout

• log onto your virtual counselor
• select test scores
• select benchmark geometry and print
• highlight the areas you are weak in (they are in red)
• then go in your geometry book and research what section(s) you can find extra help or problems to do to strengthen these weaknesses. use the table of contents or the index!
  
• otherwise, select graduation information and print---highlight the subjects that you still need to take in order to graduate. also, if highlight your college placement test scores (CPT) if you have any
