m = - 3
m = - 1/3 <-- ?
m = 3
m = 1/3

Find the slope of the line that contains the points (-2, 4) and (-4, 6).

m = -1
m = 1 <--
m = - 1/3

Find the equation of the line that passes through the points (7,4) and (-5,-2)?

y=1/2x-1/2
y=-1/2x-1/2
y=-1/2x+1/2<--
y=1/2x+1/2

Find the equation of the line that passes through the points (1,4) and (2,-8).

y = -3x + 9
y = 6x + 5
y = -12x + 16

  3. No problem. I was just working on it when you reposted.

    It had been almost two hours, and your posting was working its way down the page to obscurity, so it was understandable.

    The nuisances are people who repost every five minutes and expect someone to be monitoring their every keystroke...
