Answer:



Step-by-step explanation:
Given
Billy's Marble = x
Required
Determine a,b and c
a. Charlie's Marble
"5 more" means 5 + or + 5
Since Billy's Marble is represented with x, then Charlie's Marbles will be

b. Danny's Marbles
Having "8 fewer" means we have to subtract 8 from Billy's marble;
Since Billy's Marble is represented with x, then Danny's Marbles will be

c. Eric Marbles
Having "three times as " means we have to multiply Bill's marble by 3;
Since Billy's Marble is represented with x, then Danny's Marbles will be


The main formula is E = sum Work,
or the work is W= FxAB=E
so AB= E/F = 126/ 14 = 9m
The y intercept is where the line passes throught the y axis, or when x=0 so therfor the line is parellel to the y axis,never crossing it.
