Write the quadratic equation given the following points.
(1,-2) (2,-4) (3,-4)

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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:

hope this !

let me know
