What is the slope-intercept equation for the line below?

B

Step-by-step explanation:

Get a line of which you want to know the slope. Make sure that the line is straight. ...  

Pick which point's coordinates are dominant in your equation. ...

Set up the equation using the y-coordinates on top and the x-coordinates on bottom.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
