If point A is (2,4) and point B is (3,2) and slope is 2 what would the equation be in standard form?
Having trouble with this problem!

Once again, the same kind of question as before.
step1: find slope
(you did that correctly and got m = 2)
step2:
use yy1 = m(xx1) , where (x1, y1) is either of the given points
using (2,4)
y4 = 2(x2)
y4 = 2x + 4
standard form has both x and y terms on the left, the constant on the right.
so....
2x + y = 8
(using (3,2) has to give you the same equation, try it.)
I usually use the point not used to sub in my equation, to see if it satisfies the equation.
It does! 
Let me see if I remember this... I believe you plug in one of the points into the point slope formula
yy1=m(xx1)
(2,4) x1=2 and y1=4 m=slope in this case 2
I hope this help
