OLEGan [10]
I can see that the equation given above is a linear equation since y and x are the only variable and the degree is one. The standard form of a linear equation is written as:

Ax + By = C

We write the given equation into standard form as follows:

<span>y - 2 = 2(x - 3)
</span><span>y - 2 = 2x - 6
y -2x = -6 +2
y - 2x = -4
2x - y = 4</span>
