Answer:
m = 1/2
Step-by-step explanation:
To find the slope, all you have to do is find the rise and divide it by the run. Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point.
You can pick any two points on the line. Let's say I choose (10, 5) and (20, 10).
Let's look at the y coordinates first. You have 5 and 10. To get from 5 to 10, you have to go up 5 units. Your rise is 5. Let's look at the x coordinates now. To get from 10 to 20, you have to go up 10 units. Your run is 10.
As I said before, the slope is rise/run. In this case, we have 5/10, which can be simplified to 1/2. Your slope is 1/2.
Note that any two points on this would give you the same answer of 1/2 for this line. If I had picked (30, 15) and (70, 35), I would still get 1/2.
Hope this helped!

Answer:
Ultraviolet (UV) radiation.
Step-by-step explanation:
Mutagen is part of genetics, it is chemical or physical agent which are present in atmosphere and causes changes or mutation in the genetic materials i.e. in DNA (these changes can be permanent as well). Example of mutagen are radioactive substances, ultraviolet radiation, etc.
UV radiation is an electromagnetic radiation which is present in sunlight. It is a strong mutagen which is when absorbed by DNA can cause extreme damage, for example, uncontrolled division of skin cell can cause skin cancer, that's the reason why UV radiation is the most common mutagen to which we are exposed to when we are outside in the sunlight.
