3. Write an equation of the direct variation that includes the point (6, -2).
y = x
y=1
80%
Oy= x
y
=
x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation ( or direct variation) if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

we have the point (6,-2)

so

Find the constant of proportionality k

Simplify

therefore

The equation of the direct variation is

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
