It is simple and easy to find out about how many number combinations there are if numbers cant repeat you simply look at which combinations that you are aiming for and find out the different type of ways that you can do to get that same equal numbers that you were hoping to find is simple like 1 + 9 = 10 as same as 5 + 5 =10 its not that hard. HOPE THIS HELPS!!!
(1,9)(-1,11)
slope = (11 - 9) / (-1 - 1) = -2/2 = -1
there can be 2 answers for this...
y - y1 = m(x - x1)
(1,9)...x1 = 1 and y1 = 9
sub
y - 9 = -(x - 1) <== here is one answer
y - y1 = m(x - x1)
(-1,11)...x1 = -1 and y1 = 11
sub
y - 11 = -(x - (-1) =
y - 11 = -(x + 1) <== here is the other answer
