The linear equation is in standard form is Ax + By = C, where A, B, and C are real numbers and A and B both are not zero. All linear equations can be written in standard form.

First find the line equation using point-slope form y - y1 = m (x - x1), where m is slope.

The line equation is y - 5 = 2 (x - (-1)

y - 5 = 2( x + 1)

y - 5 =  2x + 2


Subtract y from each side

 - 5 =  2x + 2 -  y

Subtract 2 from each side

 - 7 =  2x -  y

The standard form equation is 2x - y = -7

 

I hope it helps!!! tell me if i can help any more.
