Answer:
Part a)
Part b) 
Step-by-step explanation:
Let
x------> the time in minutes
y-----> the total numbers of words
step 1
we have
-----> given table
<u>Find the slope of the linear equation</u>

with the slope m and the point A find the equation of the line
The equation of the line in point slope form is equal to

substitute


----> This is a linear direct variation
Part b) For 
substitute the value of x in the linear equation to find the value of y

Will is W years old.Ben is 3 years older.
Jan is twice as old as Ben.
If you add together the ages of Will, Ben, and Jan the total comes to 41 years
1. W+3= ben age (W+3)*2= Jan age for all three: w+(w+3)+(w+3)2
Sorry i was trying to find a simplier equation and realized i need to do part 2 before i can. I'm trying sorry!
