Use points (2001,17.60) and (2002,18.75) to write an equation in slope intercept form.

The general slope-intercept form is given by , where is the slope and is the y-intercept.

Let's find the slope first. Remember that the slope given by two points is . So, using the two given points,





Now, we know that . To find , let's just plug in the x and y coordinates for one of the points and solve for b:





Thus, the equation of the line in slope-intercept form is

$18.25 ($365 divided by 20)
