What is a graph for y=-2x-2?

Anation:
one way is to find the intercepts, that is where the graph

crosses the x and y axes
∙
let x = 0, in the equation for y-intercept
∙
let y = 0, in the equation for x-intercept
x
=
0
⇒
y
=
0
−
2
⇒
y
=
−
2
←
y-intercept
y
=
0
⇒

x
−
2
=
0
⇒
x
=
1
←
x-intercept
plot the points
(
0
,
−
2
)
and
(
1
,
0
)
draw a straight line through them for graph
