I have no idea how to do this. I have read about it many times and don't understand it.

Answer 3

ok all u need is to find
1_ any point that lies on the line (can u do that ??)

Answer 4

im stuck in the slop.

Answer 5

*slope

Answer 6

ok to find the slope u needs two point that lies on line ,, can u give me two point ??

Answer 7

(0,0) and (2,3) right?

Answer 8

(0,0) is correct but (2,3) is not try another one.

Answer 9

I dont know what else it could be but (3,2). Sorry im really bad at math.

Answer 10

well ya (3,2) is correct !
now im confused y u cant give another one u can say infinitly point the lies on this line such as
(2,1)
(5,3)
(6,4)
....
(-3,-2)

Answer 11

But, I dont understand. What do I do next. How do I find the answer?

Answer 12

huh , ok im doing it for u step by step now chose any two point u want (x1,y1)
(x2,y2)
and aply it to this formulla
m=(y2-y1)/(x2-x1)

Answer 13

is it y=2x
