How to find x and y coordinates on line? How to find where the line cutss x or y axis ...I am soo confused some one help!

if you want to find where a line cuts the y axis then let x = 0 and see what y value comes out (0,?) and vice versa if you want to find where a line cuts the X axis then let y = 0 and see what x value comes out (?,0) Hope this helps!!

1. write down the equation of the line. e.g. LINE; 3x + 2y = 12
2. For crossing the X axis ; let y = 0 3x + 2(0) = 12
3. Solve this equation 3x + 0 = 12
3x = 12
x = 4
So if x=4 and you know y = 0 then the point you want is (4,0)
For crossing the y axis, let x = 0
then you get
