Tom is looking at plans for his new house. according to the plan, 2.6 inches equals 13 feet. if the length of the wall is 18 feet how long is the wall on the plan

If the length of the wall is 18 feet, then the wall on the plan is 3.6 inches long

Solution:

According to Tom,  2.6 inches equals to 13 feet

Length of the wall = 18 feet

If 2.6 inches is equal to 13 feet, then 1 feet is equal to:

So, 1 feet = 0.2 inches …….(1)

Now, we have to determine the length of the wall on the plan which is 18 feet long

Using Equation (1), 18 feet = 18 × 0.2 inches = 3.6 inches

Hence , the wall on the plan is 3.6 inches long

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

the answer is  

a.

4,624π mm2
