What function describes a line with slope 4/3 and passing through the point (2,5) ?

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the data given we have:

Thus, the equation is of the form:

We substitute the given point and find the cut point "b":

So:

Thus, the equation is:

Finally, we have that the function is of the form, where

The function that describes the line is:
