What is the slope of the line between the points (2,-1) and (5,-3)

Ilya [14]

Answer:

The slope of the line between the points (2,-1) and (5,-3) is $m=-\frac{2}{3}$

Therefore $m=-\frac{2}{3}$

Step-by-step explanation:

Given that the line between the points (2,-1) and (5,-3)

To find the slope of the line between the points (2,-1) and (5,-3) :

The formula for slope is $m=\frac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ , $(x_2,y_2)$ be the given points (2,-1) and (5,-3) respectively

Now substitute the values of the points in the formula

$m=\frac{-3-(-1)}{5-2}$

$=\frac{-3+1}{3}$

$=\frac{-2}{3}$

Therefore $m=-\frac{2}{3}$

The slope of the line between the points (2,-1) and (5,-3) is $m=-\frac{2}{3}$

Is it a arithmetic or geometric sequence?? Please help

docker41 [41]

A geometric sequence is where you multiply by a constant number to get the next number.

An arithmetic sequence is where you add by a constant number to get the next number.

In the sequence 2, 10, 50, 250, the difference between the numbers are different, but when you multiply each number by 5, you get the next number.

This means that this is a geometric sequence.

The next term would be 250 x 5 which is 1250.
