What is the equation of the line in standard form?
x−2y=4
x + 2y = 4
2x−y=2
2x + y = 2

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

Where:

m: It's the slope

It is a point through which the line passes

To find the slope, we need two points through which the line passes, observing the image we have:

Thus, the equation is of the form:

We choose a point:

Finally, the equation is:

Now, we write the equation of the standard form :

This is equivalent to:

Option C
