Question

The table below shows the amount of money, in hundreds of dollars, Cora has saved after different numbers of years:

Years (x) 1 2 3 4 5 6
Money (y) (hundreds of dollars) 10 20 30 40 50 60


Identify the function that represents Cora's savings and the amount that Cora will have saved in 8 years.

y = x + 10, in 8 years she will have saved $1,800
y = x + 60, in 8 years she will have saved $6,800
y = 6x, in 8 years she will have saved $4,800
y = 10x, in 8 years she will have saved $8,000

Answer 1

ok you are giving the following pairs should be on your line or curve:
(1,10)
(2,20)
(3,30)
(4,40)
(5,50)
(6,60)
can you establish a relationship between x and y each time that will hold for the other points as well

Answer 2

(x,y)
the first number is x
the second number is y

Answer 3

for example is it y=x+10?
well look at (1,10)
is the equation 10=1+10 true?
