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 = 4 + 2x
What does the slope 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 receives.
D)The height of the plant increases by 4 mm for every hour of sunlight it receives.

C)The height of the plant increases by 2 mm for every hour of sunlight it receives.

Step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
