This problem wants us to use the given conditions to write an equation for the line in point slope form, passing through the point 2 -9 -3 with the x -intercept of negative 2.
00:08
And point -slope form in general form is what we see here.
00:12
And to write a line in point -slope form, we need two things.
00:15
We need the slope, and then we need a sample point that that line is supposed to go through for our x -1 and y -1.
00:20
The y -1 and the x will stay a part of the equation.
00:23
And so we already have really two points that we could use for x -1 -y -1 for either value.
00:28
But what we need is the slope because we weren't given that.
00:31
So what we're going to do is use the slope formula, y2 minus y1 over x2 minus x1 to find the slope between two points.
00:40
And we already have one point...
