Question

if y varies directly with x, find the constant variation with x= 4 and y= -26

Answer 1

The constant variation is k=-13/2

Answer 2

Answer:

k = - 6.5

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 x = 4 when y = - 26, hence

k = $\frac{y}{x}$ = $\frac{-26}{4}$ = - $\frac{13}{2}$ = - 6.5
