Determine whether the equation represents a direct variation. if it does, find the constant of variation. 7x = −6y

 Yes , it is direct variation equation.

The constant of variation

Step-by-step explanation:

We know that , the equation for the direct variation between two variables x and y is given by :-

, where k is the constant of proportionality .

The given equation :

When we divide both sides by -6 , we get

Or we can write it as  

Which is in the form of direct variation equation .

By comparing them , the constant of variation becomes :

⇒The constant of variation

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
