One way to write 18/6 is to compute 18/6 to be the whole number of a quotient that is equal to. Another way to write 18/6 is to write it as an improper fraction that's reduced. One more way to write 18/6 is as a decimal. Note how all of these ways of writing the same expression are all equal to writing one same value, and it's the WAY in which you modify what you're writing.
(-2,-5)(2,3)
slope(m) = (3 - (-5) / (2 - (-2) = (3 + 5) / (2 + 2) = 8/4 = 2
There can be 2 answers for this...
y - y1 = m(x - x1)
slope(m) = 2
(-2,-5)....x1 = -2 and y1 = -5
sub
y - (-5) = 2(x - (-2) =
y + 5 = 2(x + 2) <== this is one of them
y - y1 = m(x - x1)
slope(m) = 2
(2,3)...x1 = 2 and y1 = 3
sub
y - 3 = 2(x - 2) <== this is the other one
Choosing blue or red: 3 blue + 4 red = 7 marbles
3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability blue or red marble: 7/10
Choosing a marble that isn't blue or red: 2 green + 1 yellow = 3 marbles
Total marbles: 3 blue + 2 green + 4 red + 1 yellow = 10 marbles
Probability non-blue or red marble: 3/10
