I'm having trouble with these two questions about slopes and equation of a line:
(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,
I will do the second one.
If you are using the y = mx + b form of the equation ....
find slope:
m = (42)/(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.
