Type the equation that shows the pattern among this set of ordered pairs.
(0, 3), (1, 5), (2, 7), (3, 9)

First find the slope between any two points:



Where  are the two points

So calculating the slope:



So the slope is 

And our equation will be in the format of 
where  and 

So, now we have half of the equation:



Now to calculate b, we can plug in a point  and solve for b.

So



Lets use the point


So:


And then:


So our final equation is 

127 millimeters is the answer

Yes you do, so £1973.09 - £1473.50 = £499.59 so tim overpaid £499.59 .hope this ; )
