4x + y = 2

Explanation:

Your first step in this process is to find the slope.
y2y1x2x1 = 2210

This gives you a slope of 41

Your second step is to plug it into the point slope form with one of the points you were given.
(yy1)=m(xx1) = (y2)=41(x0)

Your third step is to simplify that into your standard form which is Ax+Bx=C
1(y2)=1[4(x0)]
y2=4x+0 Distribute
y2+4x=0 Move the x value to the other side with inverse operations.
y+4x=2 Move the C value to the other side with inverse operations.
4x+y=2 Rearrange accordingly to get into the Ax+By=C formula.
