Question

find the y - value when x = 0 by substituting into y = \frac{1}{4}x - 4

Explanation:

Step1: Identify the function

The function given is \( y=\frac{1}{4}x - 4 \) (assuming \( W \) is a typo for \( y \) and \( x \) is the input variable). We need to find the \( y \)-value when \( x = 0 \).

Step2: Substitute \( x = 0 \) into the function

Substitute \( x = 0 \) into \( y=\frac{1}{4}x - 4 \). So we have \( y=\frac{1}{4}(0)-4 \).

Step3: Simplify the expression

First, calculate \( \frac{1}{4}(0)=0 \). Then, \( y = 0 - 4=-4 \).

Answer:

The \( y \)-value when \( x = 0 \) is \(-4\).
