find the y - intercept of the line y = 2x - 9. write your answer as an integer or as a simplified proper or…

Explanation:

Step1: Recall y - intercept formula

The y - intercept of a line in the form $y=mx + b$ is the value of $y$ when $x = 0$.

Step2: Substitute $x = 0$ into the equation

Substitute $x = 0$ into $y=2x - 9$. We get $y=2\times0-9$.

Step3: Calculate the value of $y$

$y=0 - 9=-9$.

Answer:

$-9$
