What is the slope of the line that passes through (-3,-7) and (1,9)
Rus_ich [418]

To find slope, use the formula:

(y2-y1)/x2-x1)

So here is what it will look like:

(9--7)/(1--3)

Since you are subtracting a negative, then it turns unto a positive so you are adding the numbers together.  

(9+7)/1+3)

16/4

4

The slope of the line is 4/1 or 4.  Which means that you will go up or "rise" 4 and go to the left or "run" 1.


Hope this helps!

How many photons with 10 ev are required to produce 20 joules of energy?

1 joule = 6,242e+18ev

20 joule = 20 joule *6,242e+18 ev/joule =1,248e+20 ev

1,248e+20 ev / (10 ev / photon) =1,248e+19 photons.
