Every square meter of solar paneling produces 0.2 kilowatts of electricity. which of the following models this situation?
answer choices
a. linear function with a negative rate of change
b. linear function with a positive rate of change
c. exponential decay function
d. exponential growth function

B. linear function with a positive rate of change

Step-by-step explanation:

Let x represents number square meter of solar paneling and y represents the total electricity produced by x square meter of solar paneling ( in kilowatts ),

Given,

1 m² of solar paneling produces electricity = 0.2 kilowatt,

⇒ x m² of solar paneling produces electricity= 0.2x kilowatt,

⇒ y = 0.2 x

Which is the required equation that shows the given situation.

Since, y = 0.2 x is in the form of linear function y = mx + c, where m is the rate of change.

⇒ y = 0.2 x is a linear function,

Also, 0.2 > 0,

⇒ y = 0.2 x has positive rate of change.

Hence, the function that models given situation is a linear function with a positive rate of change.

Option B is correct.
