Find the slope of the line that contains the two points (3,2) and (1,4).
slope is ∆y/∆x = (42)/(13) = 6/2 = 3
Find the slope of the line that contains the points (2, 4) and (4, 6)
slope is (64)/(4(2)) = 2/2 = 1
>b>Find the equation of the line that passes through the points (7,4) and (5,2).
slope is (24)/(57) = 6/12 = 1/2
the point slope form gives
y4 = 1/2 (x7)
y = 1/2 x  7/2 + 4
y = 1/2 x + 1/2
Find the equation of the line that passes through the points (1,4) and (2,8).
slope = (84)/(21) = 12/1 = 12
y4 = 12(x1)
y = 12x  8
You got that one right.
Looks like you need to be more careful figuring your slopes.

Thank you and yes I honestly do... it's hard for me at least but I do try.
