Question

what is the slope of the line $y = -4$?
choose 1 answer:
a $-4$
b $0$
c $4$
d undefined

Explanation:

Step1: Recall slope-intercept form

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

Step2: Rewrite given line equation

Rewrite $y = -4$ to match the slope-intercept form: $y = 0x + (-4)$

Step3: Identify the slope

In the rewritten equation, the coefficient of $x$ (which is $m$) is 0.

Answer:

B. 0
