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

The price of a certain painting increased by 20% during the first year and decreased by 15% during the second year. The price of
Rina8888 [55]

Answer:

A.102%

Step-by-step explanation:

Let cost price of painting=$100

In first year price increased 20%

Then , the price=100+100(0.20)=$120

In second year

Price decreased 15%

Then , the price of painting=120-120(0.15)

The price of painting=$102

Percent =\frac{final\;price}{Initial\;price}\times 100

By using this formula

Then, we get

Percent of the original price=\frac{102}{100}\times 100

Percent of the original price=102%

Option A is true.

y = mx + b

-1 = 10(-2) + b

-1 = -20 + b

19 = b

y = -2x + 19

Hope this helps! ;)
