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

How does dividing mixed numbers compare with dividing fractions?​
nirvana33 [79]
Mixed numbers are basically sometimes a sign of division. You need to turn the mixed number into an improper fraction.

Steps:

Multiply the whole number by the denominator of the fraction and then add that product to the numerator. Leave the denominator as it is before.

Example:

2 1/4

2x4=8

8+1= 9

Answer: 9/4

Then you can divide!

kolezko [41]

Answer:

0.4 would represent the strongest correlation.

Step-by-step explanation:

Generally, a value of r greater than 0.7 is considered a strong correlation. Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation
