What is the slope of the line passing through (-3, 5) and (5, -3)?

1 answer:

5 0

Dy/dx, ie., the difference in y divided by the difference in x. If you have two points A and B, sort them in ascending order of x.

dx = 5 - -3 = 8 (x coordinates of B minus x coordinate of A)
dy = -3 - 5 = -8 (y coordinate of B minus y coordinate of A)

dy/dx = -1

So the slope is -1. The equation of the line is y=2-x.

Well, i'm just going to take a stab at this:

The answer out of:
> It is (18,9) ,
> It is (9, 18)
I believe both are correct as those are both plausible coordinates (although I may be wrong)

Line R: 2x + 2y = 18 (x + y = 9)
Line M: x + y = 9
There are infinite many solutions as they are the same line.

A man owns 3/4 of the share of a business and sells 1/3 of his

quester [9]

Given:

A man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.

To find:

The value of the business in Bir.

Solution:

Let x be the value of the business.

It is given that a man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.

$x\times \dfrac{3}{4}\times \dfrac{1}{3}=10000$
