Question

key attributes - given the following function, identify the key attributes listed. graph the function if needed. -2x + 4y = 8 identify the y-intercept. type only the numeric answer.

Explanation:

Step1: Recall y-intercept definition

The y-intercept is the value of \( y \) when \( x = 0 \). So substitute \( x = 0 \) into the equation \( -2x + 4y = 8 \).
\[ -2(0) + 4y = 8 \]

Step2: Solve for y

Simplify the left - hand side: \( 0+4y = 8 \), which is \( 4y = 8 \). Then divide both sides by 4: \( y=\frac{8}{4}=2 \).

Answer:
