We are asked to find the equation of the line in both point slope form, which is y minus y1 equals m times the quantity x minus x1.
00:14
On slope intercept form, which is y equals mx plus b.
00:18
So the first thing we have to do, we have to take the two points that they gave us that the line is going through and figure out our slope.
00:25
So if you remember the slope formula, m equals y2 minus y1 over x2 minus y1.
00:33
X1, so that's just subtracting our coordinates from each other.
00:37
And it doesn't matter what direction you subtract.
00:39
I'm going to do minus the negative 2 for my ys.
00:44
I think i have to subtract the x's in the same direction and three minus negative.
00:51
That'll give me 8 over 6, which will be the 4 thirds.
00:57
And we want to leave that as an improper fraction for substituting it into our two formulas for the equation of the line.
01:05
It's just not appropriate to put a mixed number in there.
01:10
All right, so we can write the points hope form...
