<PRE><B>Question 175725</B>
lets call x value, weeks and the y value, amount of dollars saved
:
so you points are (6,132) and (12,240)  we have two points so lets find the slope
:
240-132/12-6=108/6=54/3=18  ...so we have a m=slope=18. now lets use the point slope formula of y-k=m(x-h) where m is the slope and (h,k) is any point on the line
:
y-132=18(x-6)
:
y-132=18x-108
:
y=18x+24
:
so as you can see we have a linear equation(why because we had two points to begin with. If we had only one 1 point we wouldnt have got this to work.
