A scientist discovers a new way to produce vitamin C. In 15 hours, 678 kilograms are produced. In 25 hours, 1018 kilograms are produced. Write an equation in the form of y = mx + b for how many kilograms, y , are produced in x hours.

The equation of the line is .

Step-by-step explanation:

According to Analytical Geometry, we know that any equation of the line can be determined by knowing two distinct points on Cartesian plane. From statement we get that:

(1)

(2)

By applying the definition of the equation of the line, we form this system of two linear equations with two variables:

(3)

(4)

By algebraic mean we get the following solution:

and

And the equation of the line is .

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
