Question

1. what is the y-intercept of a line whose equation is y = -1/2 x + 4

4
1/2
-1/2
-4

Explanation:

Step1: Recall slope - intercept form

The slope - intercept form of a linear equation is $y = mx + b$, where $m$ is the slope of the line and $b$ is the y - intercept.

Step2: Identify the y - intercept from the given equation

The given equation is $y=-\frac{1}{2}x + 4$. Comparing this with the slope - intercept form $y = mx + b$, we can see that $m=-\frac{1}{2}$ (the slope) and $b = 4$ (the y - intercept).

Answer:

A. 4
