In which of the scenarios can you reverse the dependent and independent variables while keeping the interpretation of the slope meaningful? OA

ОВ.
As the age of an infant increases, the height of the infant increases.
OC. As the number of vehicles in a city increases, the amount of pollution in the city increases.
OD As the concentration of salt in water increases, the density of water increases
OE

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

where is the graph

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
