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? 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.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
