Let X equal the number of years since 1992, and let Y equal the number of participants.
Year Male Female
1992 7.18 3.44
1997 8.30 5.35
--------------
Male DATA:
You have two points: (0,7.18) and (5,8.30)
slope = [8.3-7.18]/[5-0] = 1.12/5 = 0.224
Y-intercept = 7.18
EQUATION: y= 0.224x+7.18
---------------
Female DATA;
You have two points: (0,3.44) and (5,5.35)
Find the slope, the y-intercept, and write the equation.
