Year Exchange Rate

1998 .67

1999 .67

2000 .70

2001 .74

2002 .80

2003 .81

2004 .86

2005 .87

2006 .90

2007 .99

To determine the Slope I did the following

1998 - 2006 = -8

.67 - .90 = -.23

y= .23

Divide

x = -8

The slope of the line is - 0.02875

I then tried the y intercept

y = mx +b

.90 = - 0.02875 (2006) + b

.90 = -57.6725 + b

.90

- 57.6725 = b

b = 58.5725

This is what I came up for the y Intercept (58.5725)

Doesn't seem right to me

Please Help
