Question

the value of y varies directly with x, and y = 18 when x = 6. what is y when x = 2? y = ? remember: y = kx

Explanation:

Step1: Find constant k

Substitute $y=18, x=6$ into $y=kx$:
$18 = k \times 6$
Solve for k: $k = \frac{18}{6} = 3$

Step2: Calculate y when x=2

Use $y=kx$ with $k=3, x=2$:
$y = 3 \times 2$

Answer:

$6$
