Use the table to answer the question.
Vesna [10]

Given:

The table of values of a linear relationship.

x        y

-1       -1

0       1

1        3

2       5

To find:

The equation for the given table of values.

Solution:

If a linear function passes through the two points, then the equation of the linear relationship is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

Consider any two point from the given table. Let the two points are (-1,-1) and (0,1). So, the equation of the linear relationship is

y-(-1)=\dfrac{1-(-1)}{0-(-1)}(x-(-1))

y+1=\dfrac{1+1}{0+1}(x+1)

y+1=\dfrac{2}{1}(x+1)

y+1=2(x+1)

Using distributive property, we get

y+1=2(x)+2(1)

y+1=2x+2

Subtracting 1 from both sides, we get

y+1-1=2x+2-1

y=2x+1

Therefore, the required equation is y=2x+1. Hence, the correct option is D.

Factor the polynomial:81m+48mn
Anton [14]
To factor this polynomial you will have to first find the GCF of 81 and 48 and its 3.

So then you put 3 out the parentheses. 3(----).

Then you have to see how many times 3 goes into 81m and 48m. It is 27m and 16mn.

So then this is what you get, 3(27m-16mn)

Hope it helps you!!!
