Answer:
Emma can complete the calls alone in 6 days, which means she can complete 
of the calls in one day. So, Emma’s rate per day is . Jackson can complete the calls alone in 
days, which means he can complete 
of the calls in one day. So, Jackson’s rate per day is . Because they’re working together, the time, 
, is the same for both.
Multiply across the table to find the part of the task each has completed. Use the equation work completed = (rate)(time) to fill in the last column cells.

Step-by-step explanation:
To graph the line, we require 2 points
Find the intercepts, that is where the graph crosses the x and y axes
To find the x- intercept let y = 0 in the equation and solve for x
x - 3 = 0 ( add 3 to both sides )
x = 3 ⇒ (3, 0 ) ← x- intercept
To find the y- intercept let x = 0 in the equation and solve for y
- y - 3 = 0 ( add 3 to both sides )
- y = 3 ( multiply both sides by - 1 )
y = - 3 ⇒ (0, - 3 ) ← y- intercept
Plot the points (3, 0) and (0, - 3) and draw a straight line through them
Area of entire figure = (16+12)(5)(0.5)(2)=140
Area of rectangular glass= 10*12=120
Area of wooden top= 140-120=20ft^2
