What is the slope of the line on the graph?<br> Enter your answer in the box.
Firlakuza [10]

Answer:

I think this is the answer you are looking for. (See below)

Step-by-step explanation:

From the given graph it is noticed that the line is passing through many points.

The coordinates of three given points are (1,5), (-1,-1), (-1,-7)

If a line passing through two points (x1 ,y1) and (x2, y2) , the slope of the lie is defined by, m= y2 - y1/x2 - x1

The line passing through two points (-1,1) and (1,5). So the slope of the line is, m= 5 - 1 / 1 minus -1

m=4/2

Therefore, the slope of the line is 2.

Pls if this is wrong, let me know in the comments. I'm not really good at this topic in math but I hope it helps you. Sorry if it is wrong. Have a good day. :)

8.25 greater than 8.250
viktelen [127]
If you are asking if 8.25 is greater than than 8.250, the answer would be no because any zero that is extended from the original number would still be the same.

ex: 6.2  and   6.200000000

(The zeros could go on forever and it would still be the same number)

Answer:

You can look for these:

Step-by-step explanation:

The factors of the equation:

For example, if multiplication, the factors 2x2=4

if addition, the addends 2 + 2= 4

So just look for the numbers before the equal sign and any key words in the problem.

Hope this helps!
