Answer:
You can model a data using a linear function when the dependent variable is a multiple of the independent formula plus another constant by the y-intercept. The constant multiple is represented by the slope. In real life problems, linear function is applied when you want to determine the cost given with a slope which is represented by cost per unit time. For example, the cost of wifi connection is $10/month plus $2 inclusive for phone charges. The linear function would be:
C = 10t + 2
where C is the cost and t is time in months

<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Glurpina is a polymorph alien and can grow extra limbs.
She has 3 hands and can shake everyone's hand at the alien conference in 10 minutes.
She can shake everyone's hand by 3 hands in 10 minutes.
She can shake everyone's hand by 1 hands in 10 / 3 minutes.
She can shake everyone's hand by how many extra hands in 3 minutes.
= 3/ 10 x 3
= 9/10
Thus, She can shake everyone's hand by 9/10 hands in 3 minutes.
