Question

1. what is the constant of variation for the equation y = x?

○ k = -1
○ k = 1
○ k = x
○ this equation does not represent direct variation.

Explanation:

Step1: Recall direct variation form

Direct variation is \( y = kx \), where \( k \) is the constant.

Step2: Compare with given equation

Given \( y = x \), which is \( y = 1 \cdot x \). So \( k=1 \).

Answer:

B. \( h=1 \)
