Okay, so let's look at this problem number 15.
00:03
So we have a point which is ac, okay, suppose it here.
00:10
And we know the slope of this line or of this equation is m.
00:18
Okay, so slope is m.
00:22
So now suppose we have another point, okay, x, y on this graph.
00:29
Okay, x, y is on the graph.
00:31
So let's, let's connecting this to, two lines, okay? maybe i use another color.
00:40
Maybe i use blue.
00:47
Okay, so this is a line.
00:49
So the slope is m.
00:52
So we can use this condition to write a formula, write a equation of this line...
