3y = x - 1...I am going to re-arrange this.....-x + 3y = -1

-x + 3y = -1
x - 2y = 2
---------------add...u will notice that the x's cancel
y = 1

3y = x - 1
3(1) = x - 1
3 = x - 1
3 + 1 = x
4 = x

solution is (4,1)

Which of the following rules could represent the function shown in the table?
kvasek [131]
ANSWER

The rule is given by the relation,

y = 2x + 1


EXPLANATION

We need to check and see if there is a constant difference between the y-values.


1 -  - 1 = 2 = 3 - 1


We can see that, there is a constant difference of 2.

This means that the table represents a linear relationship.


Let the rule be of the form,
y = mx + c


Then the points in the table should satisfy the above rule.


So let us plug in


(0,1)


This implies that,


1 =m (0) + c


1 = 0 + c


c = 1



Our rule now becomes,


y = mx + 1 -  - (1)


We again plug in another point say, (-1,-1) in to equation (1) to get,



- 1 = m( - 1)   + 1

we solve for m now to obtain,

- m=-1-1


- m =  - 2


m = 2
We now substitute back in to equation (1) to get

y = 2x  + 1
