Can the points below represent values of a function? Explain (in words). Use a Strategy. (1,7) (3,16) (5,19) (5, 20) (9,28)

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

80

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
