Question

find the y-intercept of the line x + y = 7. write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.

Explanation:

Step1: Recall y-intercept definition

The y-intercept of a line is the value of \( y \) when \( x = 0 \).

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

Given the line \( x + y = 7 \), substitute \( x = 0 \):
\( 0 + y = 7 \)
Simplify to get \( y = 7 \).

Answer:

\( 7 \)
