i got u
Answer:
The slope is
−
2
5
.
The y-intercept is
1
.
The point is
(
0
,
1
)
.
The x-intercept is

.
The point is
(

.
Explanation:
y
<
−
2
5
x
+
1
is in the slope-intercept form of a linear equation,
y
=
m
x
+
b
, where m
is the slope and b
is the y-intercept. The y-intercept is the value of y
when x is 0
.
Find the
x and y
intercepts.
The y-intercept is +
1
.
The point for the y-intercept is
(
0
,
1
)
.
Find the x
intercept by substituting
0 for y
and solving for
x
. 0
=
−
2
5
x
+
1
Subtract 1
from both sides.
−

Multiply both sides by

x
Divide both sides by −

Plot the two points on a graph. Draw a straight dashed line through the points to indicate that the line is not part of the inequality. Then shade the area below the line.
