We know that a positive and a negative will end in a negative result. (+) (-) = (-)
The rule to remember about generating the perpendicular family to a line is we swap the coefficients on and x and y, remembering to negate one of them. Then the constant is set directly from the intersecting point.
So we have
y = 3x + 2
-3x + 1y = 2
Swapping and negating gets the perpendiculars; the constant is as yet undetermined.
1x + 3y = constant
Since we want to go through (0,2), we could have just written
x + 3y = 0 + 3(2) = 6
3y = -x + 6
y = (-1/3) x + 2
Third choice
Answer: A floating-point number is one where the position of the decimal point can "float" rather than being in a fixed position within a number. floating point is a variable type that is used to store floating-point number values.
