How many different strings can be made from the letters in HAPPINESS, using all the letters?

20 different strings

Step-by-step explanation:

Let the lines in the alphabets be the strings. So, each alphabet has many strings. Counting them would make them 20 strings.

m = 3/2, y intercept = 3

Step-by-step explanation:

The y intercept is where it crosses the y axis.  It crosses at 3

The slope is  found by using two points on the line

(-2,0) and (0,3)

m= (y2-y1)/(x2-x1)

   = (3-0)/(0- -2)

  = 3 / +2

  =3/2
