Answer:
Plot the point with the y-intercept
(
0
,
−
3
)
. Use the slope
2
1
to move up 2 and over 1 to find a second point at
(
1
,
−
1
)
. Draw a straight line through the points.
Explanation:
y
=
2
x
−
3
is in slope intercept form for a linear equation,
y
=
m
x
+
b
, where
m
is the slope and
b
is the y-intercept.
The y-intercept is the point at which
x
=
0
and
y
=
−
3
, which is point
(
0
,
−
3
)
You can plot this point on your graph.
The slope is can be described as
rise
run
, and can be written as
2
1
. Start at
(
0
,
3
)
. The next point would be found by moving up 2 and over 1. This would give point
(
1
,
−
1
)
. You can keep doing this as long as you want, but for a straight line, you really only need two points.
Draw a straight line between the two points.
