So let's take a look at some equations of lines.
00:08
So let's say we have a linear equation, right? let's say that's y equals negative 750x plus 10 ,800.
00:27
So let's say that this represents the amount of paint that a paint company has on hand on any given day, right? now, what would this look like in a graph? and so in a graph, right, we're going to need some points.
00:57
And so we could create a table, right? so we could have our x, y table here, right? right zero one two three four and right x is going to represent the amount of days y tells me how much paint the store actually has on hand each day right so we could substitute the numbers in so zero we're going to get right 10 ,000 800 if we plug one in there we would get 10 ,000 and 502 would give us 9 ,300.
01:43
We substitute 3 in there.
01:46
We would get 8 ,550.
01:50
And then if we substitute 4 in there, we get 7 ,800.
01:59
And so here are our points.
02:00
And so now we can graph them, right? the numbers are very large and so when i graph i'm going to i am going to start a little higher than normal right so i see at 4 we've got 7 ,000 so let's say this is 7 ,000 8 9 10 like 11000 up there right so this would be be about 10 ,000...
