All right, we're going to graph our equation.
00:06
So we can use the variables given.
00:09
A for award of federal assistance is equal to 0 .08 multiplied by the number of years since 1994.
00:23
And we're going to start with 2 .5.
00:28
So you can scan our graph, the starting point, or the y8.
00:32
Intercept is at 0 comma 2 and a half and then my slope is going to go over 1 up 800s over 1 up 800s, over 1 of 800s, okay? here i've chosen a scale of 10 on my x -axis going up to 100 and i've chosen just going up to 10 on my y -axis and a scale of 1.
01:02
So if we want to estimate, if we want to show on our graph 18 years later, so in year 2012, minus 18 is 1994.
01:15
So the years since 1994 to 2012 would be 18 years.
01:19
We're going to want to substitute the 18 and for t since t is representing the number of years since 1994.
01:26
So in my equation over here, i can put 0 .0 .0.
01:33
And i'm going to multiply it by 18 and we are going to add a two and a half...
