Find the slope of the graph shown

-2 over 3 (-2/3)

When looking for the slope of a graph, you wanna use a process called “rise over run”.
It’s simple because you’re using information given to you by the graph!

Choose two points, I chose (-2,4) & (1,2)
Now use [rise/run]
RISE is the number of how much the graph rises vertically from the point farthest to the left to the point farthest to the right.
RUN is the number of how much you will travel from left to right, from one point to the other.
For this problem, we’re going down instead of up, so the rise will be negative. (-2)
For our run, we traveled 3 units to the right, so the run will remain positive. (3)

If the rise went up (positive), the sign would be positive (+)
If the run went to the left (negatively), the sign would be negative (-)

I really hope this helps :)

The writing is like bold so i can’t see it well

Hello!

the answer is:

the correct option is the option b.

why?

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
