Explain linear function. Provide a real-world example of linear function, explain the rate of change. Include reference(s) in your post.

Step-by-step explanation:

A linear function : Linear functions are those whose graph is a straight line.

 , A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.  a is the constant term or the y intercept. It is the value of the dependent variable when .  b is the coefficient of the independent variable.

In real life, we know that voltage is directly proportional to current , having resistance as a proportionality constant or more precisely slope of line :

, slope remains constant but , voltage is directly proportional to current .

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

the answer is 18 units because there are 18 small cubes inside the rectangle
