Answer:
The answer is
Step-by-step explanation:
In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.
In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.
We divide each side by "W":
We simplify the "W" in the right side:
Finally, the solution for "L" is :
Given:
The graph passes through the points (0,-20) and (4,10).
To find:
The equation of line that most closely represents the line depicted in the graph.
Solution:
If a line passing through two points, then the equation of line is
The given line passes through the points (0,-20) and (4,10). So, the equation of line is
Subtracting 20 from both sides, we get
The function form is
f of x equals fifteen halves times x minus 20.
Therefore, the correct option is B.
