Which of the following is a point-slope equation for a line with the point(-2,4) and a slope of 3?
A. y - 4 = 3(x - 2)
B. y - 4 = 3(x+2)
C. y-2 = 3(x-4)
D. Y + 2 = 3(x-4)
Please answer asap

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

point-slope formula: y-y1 = m(x-x1)

y1 = 4 ; x1 = -2 ; m (slope) = 3

plugging it in to the formula, you get y-4 = 3(x-(-2)

then you get y-4 = 3(x+2)

What is Scientific notation?

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. Scientific Notation is the expression of a number n in the form a∗10b. where a is an integer such that 1≤|a|<10. and b is an integer too.

Given :

The given number is

20,612,439

in scientific notation is

$2.0*10^(7)$

Move the decimal point so that there is seven non-zero digit to the left.

Hence, the scientific notation of the population is $2.0*10^(7)$ .

You should know that if you want to write something on your computer, that you should open Word or some other program in which you can write, for example.
