Answer:
D
Step-by-step explanation:
12x + 6y = 24
Subtract 6y on both sides.
12x = 24 - 6y
Divide 12 into both sides.
x = 24/12 - 6/12y
x = 2 - 1/2y
Answer:
exact form - b = -11/5
decimal form - b = -2.2
Mixed number form - b = -2 1/5

Answer:
A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in the natural sciences and engineering disciplines, as well as in non-physical systems such as the social sciences.
The slope-intercept form:

m - slope
b - y-intercept
<em>subtract x from both sides</em>
<em>change the signs</em>

It's a linear function.
We need only two points to plotting a graph.
We choose any three values of x and calculate y.
