For this problem, we've been asked to find the equation of a line with a given slope that passes through a given point.
00:06
So for this problem, we're told that our slope is 14, and the point that we want to go through is negative 1, 0 .3.
00:17
Okay, so how do we use this information to write the equation of a line? well, one common way to write a line is our slope intercept form, which is y equals mx plus b.
00:28
This is not very helpful in this case because we're given a point, not the y intercept.
00:36
So what form uses a point and the slope? well, we're going to use, it's not very imaginatively named, it is called the point slope form.
00:46
And that form looks like this.
00:49
Y minus y1 equals m times x minus x1.
00:54
We call it the point slope form because it uses a point.
00:58
Make sure you put the x's and y coordinates in the right position, but it has a point, and it uses a slope.
01:05
And just like with our other format, m is usually represents the slope in this type of equation...
