Question 740003: Find the slope, if possible, of the line passing through each pair of points.
1.) (2,-1)and (6,3)
2.) (4,0) and (3.8,2)
3.) (4,11) and (-2,1)
4.) A line K passes though the points (4,2)and(-4,4). A second line H passes through the points (-8,1)and(8,-3). Is the line K parallel to line H? Why or why not?

Find the slope, if possible, of the line passing through each pair of points.
1.) (2,-1)and (6,3)
Slope, m = diffy/diffs
m = (-1-3)/(2-6) = -4/-4
m = 1
================
2.) (4,0) and (3.8,2)
Same as above
3.) (4,11) and (-2,1)
Same as above
4.) A line K passes though the points (4,2)and(-4,4). A second line H passes through the points (-8,1)and(8,-3). Is the line K parallel to line H? Why or why not?
Find the slope of each line. Parallel lines have the same slope.
