Question

The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm, to which it grows: y = 2 + 4x What does the y-intercept of this function represent? (1 point) The original height of the plant was 4 mm. The original height of the plant was 2 mm. The height of the plant increases by 2 mm for every hour of sunlight it receives. The height of the plant increases by 4 mm for every hour of sunlight it receives.

Answer 1

Answer:

The original height of the plant was 2 mm

Step-by-step explanation:

Given

$y = 2 + 4x$

Required

Interpret the y-intercept

The y-intercept is when $x = 0$

So, we have:

$y = 2 + 4 *0$

$y = 2 + 0$

$y = 2$

This implies that the original or initial height was 2 mm
