4. 1. A ball is rolled down a hallway and its position is recorded at five different times. Use the data given in the table shown below to predict the location of the ball at 12s 2. What is the equation represented by this data? 3. How linear is the data? What is the correlation coefficient?

5. Section 2.4

6.  A linear equation has 2 variables.  There are an infinite amount of solutions of a linear equation ◦ The value of y is normally dependent on the value of x  All solutions of linear equations are ordered pairs (x,y)  The graph of any linear equation is a line

7.  Standard Form Ax + By = C ◦ Most basic form of linear equations. ◦ Ex: 2x – 3y = 55  Slope Intercept Formy = mx + b ◦ Most popularly used ◦ m = slope, b = y-intercept ◦ Ex: y = 4x - 1

8. A.y = 3x + 4 B.y = 4x + 3 C.y = 4x D.y = 4 Write an equation in slope-intercept form of the line whose slope is 4 and whose y-intercept is 3.

9.  Write an equation to represent the following: ◦ Each hour a candle burns down the ¼ of an inch. The candle is 6 inches tall.  x = the number of hours that have elapsed.  y = the height of the candle in inches. ◦ When sending a letter, you pay $0.49 you then pay $0.05 smaller, fixed amount for each additional ounce.  x = the weight of the letter in ounces.  y = the cost of sending the letter in cents. ◦ A group going on Senior trip pay $850 to rent a bus for a day. The total cost of the bus is shared equally among the passengers.  x = the number of passengers.  y = the cost for each passenger in dollars. ◦ My car loses about half of its value each year. It is currently valued at $15,000. What is the value in 3 years?

10.  Determines steepness of a line  Can be positive, negative, zero, or undefined  Formula:  Symbol: m  Parallel lines have the same slope  Perpendicular lines have slopes that are opposite reciprocals  SAME thing as rate of change!!!! ( how much it changed/ how long it took to change y 2 -y 1 x 2 -x 1

11.  x intercept: Where the graph of the equation crosses the x axis ◦ To find the x int, set y= 0, solve for x  y intercept: where the graph of the equation crosses the y axis ◦ To find the y int, set x= 0, solve for y

12. - Get y by itself - Put it in your calculator - Use trace function to get ordered pairs

13. Graph 3x + 2y = 6. A.B. C.D.

14. Graph 5y = 10. A.B. C.D.

15. Original inequality Add 4x to each side. Simplify. Divide each side by 2.

16. A.B. C.D. Graph y – 3x < 2.
