    To find x-intecepts, you let y = 0 and solve for x

    To find y-intercepts, let x = 0 and solve for y

    but how would i do that if there's no y in the equation??

    is 3x = 10 the complete equation?

    then if you solve that, you get x = 10/3, which is a vertical line. It will pass thru the x-axis at (10/3, 0) and it will never cross thru the y-axis, so it has no y-intercept

    and the class that i'm in is a computer based learning. so there's no teacher to teach

    a vertical line has no y-intercept.

    You would just have to say none, or does not exisit for y-intercept

    Does it specifically ask for x- and y-intercept? or just 2 pts on the line?

    two points on the line to be graphed and enter their coordinates in the boxes below

    i just tried that answer.. and it came up wrong and now they gave me a different question.. now it's 4x=4

    that's different.....if it's a vertical line x = 10/3, then no matter what y value you have, the x-value is ALWAYS 10/3

    ok, same thing....now, what does x = ?

    the equation just reads 4x=4

    Now if you solve, you get x = 1

    yeah, I meant if you solved for x.....so the equation is x = 1. Now matter what the y-value is, x ALWAYS = 1

    so, use the ordered pair (1, any y-value)

    it could be (1, 3) or (1, -10), or (1, 5).....the y-value doesn't matter
