Okay, we're given the slope and a point in a line and ask to find three other points.
00:09
There are multiple ways we could go about this.
00:12
We could of course write an equation for the line using the point slope form, but we can also just do it graphically.
00:21
So let's start there.
00:23
So let's plot that point, negative 5, 4.
00:29
We have that.
00:31
If we want to find other points on this line, and we know the same, slope, we can just start at that point.
00:39
Remember that slope is the rise, it's the change in y over the change in x.
00:50
So for every one that x changes, y changes to.
00:59
Remember, because it's a positive slope, the line will go this way.
01:07
If it were a negative slope, the line would slant this way, right? so, because it's a positive slope for every change of 2 and y, x changes 1.
01:25
If we wanted, we could even draw a little stir -step ladder.
01:28
Same thing.
01:29
Negative 2, negative 1 continues so that we have a positive slope of 2...
