When you add two opposite numbers (4/5 is the opposite of [-4/5]) the answer is always zero.
Answer:

or in slope y-intercept form :

Step-by-step explanation:
The easiest way of find the answer for this is to use what is called the "point-slope" form of a line, because you are in fact given the value of the slope (m) and also a point
it goes through:

In our case the equation becomes:

This can also be written in the slope-intercept form by solving for "y" and operating to remove the parenthesis:

Sorry but u should write ur expression so i can solve it....
