Creating a Table of Values Algebra A Unit 5, Lesson 2

Let’s graph y = 3x – 2 Make a Table of values 2 1 0 –1 –2 yx y = 3(–2) – 2 = –8 y = 3(–1) – 2 = –5 y = 3(0) – 2 = –2 y = 3(2) – 2 = 4 y = 3(1) – 2 = 1 –8 –5 –2 1 4 www.chaoticgolf.com/pptlessons/graphinglinearequations.ppt

Quick Check

At a ball game they charge \$2 for a hotdog. The function C(h) = 2h describes the cost of h hotdogs. Use the points for each input value. hC(h) = 2h (h, C(h)) 1C(1) = 2(1) (1, 2) 2C(2) = 2(2) (2, 4) 3C(3) = 2(3) (3, 6) 4C(4) = 2(4) (4, 8)

At the local video store you can rent a video game for \$3. It costs you \$5 a month to operate your video game player. The total monthly cost C(v) depends on the number of video games v you rent. Use the function rule C(v) = 5 + 3v to make a table of values and a graph. vC(v) = 5 + 3v (v, C(v)) 0C(0) = 5 + 3(0) (0, 5) 1C(1) = 5 + 3(1) (1, 8) 2C(2) = 5 + 3(2) (2, 11)
