Monday: For Exercises 1 & 2, determine whether each linear function is a direct variation. If so, state the constant of variation. 1. 2. State the slope and the for the graph of each equation. (#5 and #6 you need to get Y alone first!!) y-intercept 5. 2x = 6. + 4x = 2 7. = 3 y – –1 y y – x – Graph each equation using the slope and the y-intercept. 8. = 3x 3 9. = + 1 10. = 2 y y y x – –x – Tuesday: State the and of each function. Please SHOW ALL work on a separate sheet of paper!!! x- y-intercepts 1. + 8y = 24 2. 6y = 18 3. = 12 4. + = 1 x y –6x – − State the and of each function. Then graph the function. x- y-intercepts 5. 4x + 2y = − −8 6. FARMING Mr. Jeans raises cows and chickens on his farm. Altogether, his cows and chickens have 140 legs. This can be represented by the function 4x + = 140. Graph the function. Then interpret the and y x- y-intercepts. 7. MONEY Monty has a total of $290 in ten dollar and five dollar bills. This can be represented by the function 10x + 5y = 290. Interpret the and x- y-intercepts. Wednesday: SLOPE Review! Please use all of your knowledge about SLOPE (use notes if needed). 1. Find the -intercept & the -intercept of the line below, then graph the equation. a. b. c. x-intercept: ________ x-intercept: ________ x-intercept: __________ y-intercept: ________ y-intercept: ________ y-intercept: __________
