What is the equation in point−slope form of the line passing through (1, 2) and (2, 5)? (5 points)

A.) (y − 2) = −3(x − 1)

B.) (y − 2) = 3(x − 1)

C.) (y − 1) = −3(x − 2)

D.) (y + 2) = 3(x + 1)

Please make sure the answer is correct

B

Step-by-step explanation:

First, find the slope by using change in y divided by change in x.

Change in y = 5 - 2 = 3

Change in x = 2 - 1 = 1

This means that the slope is 3/1 = 3.

Then, you put it in the point-slope form so:

(y - 2) = 3(x - 1)

parallelogram is the   answer

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
