Suppose the y varies directly with x and y=8 when x=-6 what direct variation equation relates x and y what is the value of y when x=-2

A. Y=-0.75x,1.50
B. Y=-1.33x,2.67
C. y=1.33x,2.67
D. Y=0.13x, -0.25

B

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition that y = 8 when x = - 6, thus

k = = = - ≈ - 1.33

y = - x ← equation of variation

When x = - 2, then

y = - × - 2 = ≈ 2.67

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
