(A)-Find the slope of each segment

(B)-Write an equation of the line that is determined by each pair of points

1. (0,0) and (6,-4)

2. (-3,2) and (7,-4)

Thank you!

**Reiny**, Saturday, February 20, 2010 at 3:53pmI will do the second one.

If you are using the y = mx + b form of the equation ....

find slope:

m = (-4-2)/(7-(-3)) = -3/5

then y = (-3/5)x + b

sub in (-3,2)

2 = (-3/5)(-3) + b

2 = 9/5 + b

2 - 9/5 = b

b = 1/5

then y = (-3/5)x + 1/5

do #1 the same way.
