Remember that the y-intercept is obtained when the value of x is set to zero. This means that the y-intercept is the value of the height without sunlight yet. This also refers to the original height of the plant. This gives:

So, the original height of the plant is 4 mm.
The formula also indicates that when sunlight is present, a height of 2mm is increased every hour of sunlight exposure.
