Question

choose the equation of the horizontal line that passes through the point (−2, −1). y = −1 y = −2 x = −2 x = −1

Answer 1

For a horizontal line, gradient is zero;
y=mx+c
since m=0
y=c
Replacing for y from given point;
-1=c
c=-1
y-1

Answer 2

Answer:

$y=-1$

Step-by-step explanation:

A Horizontal Line has equation of the form  $y=a$  where $a$ is the y-coordinate.

The point here given in this problem is  $(-2,-1)$

What's the y-coordinate? It is $-1$

So the Horizontal Line equation will be  $y=-1$
