Answer:

Step-by-step explanation:

You need 2 columns and 4 rows of data here:

x y

1 30

2 60

3 90

4 120

Each time x increases by 1, y increases by 30, so the relationship between x and y is y = previous y + 30. This is the 3rd answer choice.

Which of the following is the correct equation for the distance formula for the points (x1, y1) and (x2,y2)?

svp [43]

Answer:

A. D=sqrt( (x2-x1)^2+(y2-y1)^2 )

Step-by-step explanation:

The distance between two points is the root of the sum of the squares of the differences in their corresponding coordinates. The equation of choice A is the usual formulation.

<em>Comment on answer choices</em>

Because the square of a number is the same as the square of its opposite, the formula in choice D is also correct.
