Which statement best explains whether y = 2x − 3 is a linear function or a nonlinear function?

it is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.

it is a nonlinear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are not on a straight line.

it is a linear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are on a straight line.

it is a nonlinear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are not on a straight line.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

step-by-step explanation:

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years
