Question

Find an equation for the line:

through (–4, –8) and horizontal.
a.
y = –8
b.
x = –8
c.
x = –4
d.
y = –4

Answer 1

horizontal lines are where the y values are constantly one number so y=that number
What is your y in the point given on this line ?

Answer 2

y = mx + b
since the line is horizontal it has no slope (m)
y = 0x+b
y = x + b
b is the y intercept; y is the y coordinate
y = 0x + b
-8 = x + b
-8 = -4 + b
-8 = -4 + -4
-8 = -8
d

Answer 3

So would the answer be A Y= -8

Answer 4

yea
the y-coordinate of your point is -8
and your line is horizontal so it is y=-8
