00:01
Write the linear function whose graph passes through the point 79 and 517.
00:08
So what do we have so far? we have two points given to us, which are, i'm just going to write them bigger because i can see it clearly when i do write it out here.
00:19
79 and 517 are our two points that were given to us.
00:25
And they want us to solve for the line equation.
00:31
So let's just do a little bit of a graph here so we can picture it.
00:36
So this is our x -axis and our y -axis.
00:39
Okay, so we have seven -nine.
00:41
So let's just pretend this is a graphing paper.
00:44
You can do it in your home.
00:45
That would be even better with a graph paper.
00:47
So this is one, two, three, four, five, six, seven.
00:53
And it wants this.
00:54
So this is seven.
00:56
And this is, we've got to go up to nine.
00:58
One, two, three, four, five, six, seven.
01:01
Eight, nine.
01:03
So our first point is roughly around here, and this is seven, nine.
01:08
Okay.
01:10
And then our next point is five, seventeen, seven, nine, uh, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, sixteen, seventeen, seventeen.
01:20
So this is seventeen and five.
01:24
Okay, so this is one, two, three, four, five.
01:27
And we want to go straight up to seventeen.
01:30
And this is our next point, which is 517.
01:37
All right.
01:38
So, as you know, two points can make a line if we connect them.
01:43
So let's do that right now.
01:45
Let's just do the dotted line first so that we can follow the line and make our line...
