  1. Tuesday, September 10th Please complete the warm up  Solve: Is (3,4) a solution to the following system: 3x-4y=12 and -4x=y+2

  2. Solution of a system of linear equations System of Linear Equations Do you know your Vocab?

  3. Slope Intercept Form Y = mx + b Slope Y-intercept

  4. b m Rise Over _____________ The _________intercept It’s where you _____ your graph GraphingY=mx + b

  5. REVIEW ON RISE AND RUN DESCRIBE how you would graph given the following slope Slope = -3 • Down 3 • Right 1 Or • Up 3 • Left 1

  6. Step 2 Slope = Count 2 units down and 5 units right from (0, 4) and plot another point. Graphing Just Watch y intercept = 4 y • Rise = –2 • • Step 1. The y-intercept is 4, so the line contains (0, 4). Plot (0, 4). • Run = 5 Step 3 Draw the line through the two points

  7. Y = -3x = 4 What is the slope?

  8. 3 – 5x = y What is the y-intercept?

  9. What is the Slope?

  10. What is the Equation that represents this line?

  11. Word Problems

  12. Slope Intercept Equation: Y=mx + b Standard Equation: Ax+By=C • Savings Account and how much you put in it each month • Cell phone starting cost and rate you pay each month • Gym membership and a rate you pay each year • Pages you read and how many pages you read each night • Down payment and your monthly payments m=rate b=starting fee Y=mx+b • How man drawings did each person make • How many shirts and socks you can buy • How many tickets you can buy • How many books you can read ALWAYS DEFINE YOUR VARIABLES FIRST X and y will be in your question! Types of Word Problems

  13. Slope Intercept Word Problem Sam and Joe are collecting baseball cards. Sam already had 5 baseball cards and is given 4 new cards each year. Joe only started with 3 baseball cards but is given 6 new cards each month. After how many months will Same and Joe have the same amount? How many cards will they have at that time?

  14. Standard Form Word Problem Jenna has $100 to spend on 3 new items of clothing. Jeans cost $50 and shirts cost $25. How many jeans can she buy? How many shirts can she buy?

  15. You decide…. You are selling tickets for a high school play. Student tickets cost $4 and general admission tickets cost $6. You sell 525 tickets and collect $2876. How many of each type of ticket did you sell?

  16. Slope – intercept or Standard Jessie has $100 to spend at Best Buy. She can only buy 9 items. CD’s Cost $12 and DVD’s cost $20. How many of each can she buy?

  17. Slope – intercept or Standard Lexi and Ryan are reading the same book. Lexi is on page 20 and reads 10 pages each night. Ryan is only on page 8 but plans to read 18 pages each night. When will they be on the same page?
