Guest (Customer)
[00:00:02] hi

Edythe C (Tutor)
[00:00:11] Welcome to Tutor.com ! Let's get started.
[00:00:22] can you type or draw your problem?

Guest (Customer)
[00:00:41] ok

Edythe C (Tutor)
[00:00:51] great

Guest (Customer)
[00:01:04] find the unknown value using the given slope and points on the line.
[00:01:41] m=0;(0,7),(3,y)
[00:02:40] hello

Edythe C (Tutor)
[00:02:56] so the slope is zero?
[00:03:52] is that correct?

Guest (Customer)
[00:03:51] yeah

Edythe C (Tutor)
[00:04:19] when the slope is zero, what kind of line do we have?

Guest (Customer)
[00:04:41] horizontal

Edythe C (Tutor)
[00:04:51] yes!
[00:04:55] very good

Guest (Customer)
[00:04:59] thanks

Edythe C (Tutor)
[00:05:52] can you put in the first point?

Guest (Customer)
[00:06:12] (0,7)

Edythe C (Tutor)
[00:06:36] can you put that on the board?
[00:07:32] right!
[00:07:49] now the 2nd point says the X part is what?

Guest (Customer)

Edythe C (Tutor)
[00:08:46] so since we need to have a horizontal line, what do you think Y is?

Guest (Customer)
[00:09:15] something that is inder it

Edythe C (Tutor)
[00:10:12] well we have one point plotted, and the Y of that point is where the line goes through the Y-axis

Guest (Customer)
[00:10:16] ok

Edythe C (Tutor)
[00:10:50] the horizontal line must have that point on it

Guest (Customer)
[00:11:02] ok

Edythe C (Tutor)
[00:11:27] the horizontal line will be parallel to the X-axis

Guest (Customer)
[00:11:33] oh ok';

Edythe C (Tutor)
[00:11:48] can you draw the horizontal line?
[00:12:05] great
[00:12:35] now starting at X=3, go up and tell me what Y is

Guest (Customer)
[00:13:21] 3,3

Edythe C (Tutor)
[00:14:10] can you see that (3,3) is not on the horizontal line?
[00:14:45] (3,?) is on the horizontal line?

Guest (Customer)
[00:14:52] 6

Edythe C (Tutor)
[00:16:01] can you see that (3,6) is not on the horizontal line?

Guest (Customer)
[00:16:17] 7

Edythe C (Tutor)
[00:16:26] yes!

Guest (Customer)
[00:16:51] oh wow that was so simple but it took me forever

Edythe C (Tutor)
[00:17:46] when the slope is zero, the line is horizontal, so the equation of the line is Y = 7
[00:18:00] so no matter what X is, Y is always 7

Guest (Customer)
[00:18:06] oh ok

Edythe C (Tutor)
[00:18:13] make sense?

Guest (Customer)
[00:18:13] can u help me with one more

Edythe C (Tutor)
[00:18:43] I'm sorry but I need to help another student

Guest (Customer)
[00:18:45] m=-2.5;(w,2),(4,-3)
[00:18:48] oh plz

Edythe C (Tutor)
[00:18:57] you can log back on for another tutor

Guest (Customer)
[00:18:57] ok

Edythe C (Tutor)
[00:19:09] good luck!
