Standard form is ax+by=c where a,b, and c are integers and a is usually positive
so first find slope get into form y=mx+b where m is slope so slope between points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1) points (-1,5) and (1,2) slope is (2-5)/(1-(-1))=-3/(1+1)=-3/2 y=-3/2x+b find b sub a point (1,2) 2=-3/2(1)+b 2=-3/2+b 4/2=-3/2+b 7/2=b
y=-3/2x+7/2 add 3/2 both sides 3/2x+y=7/2 times 2 both sides 3x+2y=7 is standard form
