The function below models the correlation between the number of hours a plant is kept in sunlight x in the height y, in mm to which it grows. y = 2 + 4x what does the y-intercept of this function represent? a.) the original height of the plant was 4 mm. b.) the original height of the plant was 2 mm. c.) the height of the plant increases by 2 mm for every hour of sunlight it receivesd.) the height of the plant increases by 4 mm for every hour of sunlight it receives.

   B.) the original height of the plant was 2 mm.

Step-by-step explanation:

The given function below models the correlation between the number of hours a plant is kept in sunlight 'x' in the height 'y', in mm to which it grows.

To find the y intercept of the function, we substitute the value of x =0 , we get

Hence, the original height of the plant = 2 mm

Therefore, the y intercept of the function is (0,2)

i.e. the original height of the plant = 2mm.

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.
