Linear equations are used to represent relations that have constant rates
The linear regression equation that models the data in this table is 
<h3>Regression equation using a graphing calculator</h3>
To calculate the regression equation, we make use of a graphing calculator.
Using the graphing calculator, we have the following data:
- Sum of X = 28
- Sum of Y = 70
- Mean X = 3.5
- Mean Y = 8.75
- Sum of squares (SSX) = 42
- Sum of products (SP) = 101
<h3 /><h3>Formulating the regression equation</h3>
The regression equation is represented as:

Where:
and 
So, we have:


Also, we have:



Hence, the linear regression equation is:

Sunlight from the sun hits the leaf of the plant.
Answer:
Option (d).
Explanation:
Equilibrium may be defined as the state of the equality on both the sides of the reaction. Different types of equilibrium are physical equilibrium, chemical equilibrium and dynamic equilibrium.
Chemical equilibrium may be defined as the equilibrium in which the reactants and products concentration remains constant with time. The rate of the backward reaction is equal to the rate of forward reaction.
Thus, the correct answer is option (d).
