y - 9 = -2(x - 8)

**visoth**, Monday, April 30, 2012 at 5:42pmfirst put it in slope intercept form

y=mx +b

m is the slope and b will give you the y intercept

y-9 = -2(x-8)

multiply everyting in the parenthesis by -2

y-9= -2x + 16

and then plus 9 from both side

y= -2x + 25

your slope is -2

**Reiny**, Monday, April 30, 2012 at 5:48pmthe equation is in the form

y - y1 = m(x - x1) where (x1, y1) is a point and m is the slope.

By the "just-looking-at it" principle, the slope is -2

(and a point on it is (8,9) )
