What is the correct equation for direct variation that includes the point (6, –3)?

Anika [276]3 years ago

A direct variation equation always takes the form y=kx, where k is a constant

Let's plug in the values of x=6 and y= -3 to solve for the value of k

-3 = k(6)

Let's flip this equality so we have the k on the left side of the equation.

6k = -3

Let's divide both sides by 6

k = -3/6

Now, simplify the fraction 

k = -1/2

Now that we found the value of k, our equation is

y = (-1/2) x

Have an awesome day! :)

Answer:

The cost of each ice cream cone is $4.50

The cost of each ice cream basket is $3.75

The cost of each donut is $1.50

Step-by-step explanation:

Let

x-----> the cost of the ice cream cone

y----> the cost of the ice cream basket

z---> the cost of the donut

we know that

2x+y=12.75 ------> y=12.75-2x ------> equation A

x+2z=7.50 ------> z=(7.50-x)/2 -----> equation B

x+y+z=9.75 ----> equation C

substitute equation A and equation B in equation C and solve for x

x+(12.75-2x)+((7.50-x)/2)=9.75

Multiply by 2 both sides

2x+25.50-4x+7.50-x=19.50

3x=25.50+7.5-19.50

3x=13.5

x=$4.50

Find the value of y

y=12.75-2(4.50)=$3.75

Find the value of z

z=(7.50-4.50)/2=$1.50

therefore

The cost of each ice cream cone is $4.50

The cost of each ice cream basket is $3.75

The cost of each donut is $1.50
