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?
yes it is
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
ok i see that point. but it tells me to find the two points. and all this is just confusing..
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
ok. i'll try that out.. thank you so much for your help... i appreciate it very much
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
ok thank you
