Which linear inequality is shown on the graph?
2 answers:
Answer:
Option A
Step-by-step explanation:
The given graph is a solid line passing through two points ( -4, 0) and ( 0, -1 )
Let the equation of this line is y = mx+c
Where m = slope of the line =
= = -
and y-intercept c = (-1)
therefore, equation will be y = ( )x + (-1)
y =
4y = -x -4
x + 4y = -4
Since shaded region is above the line therefore inequality will be (x+4y ≥ -4)
Option A is the answer.

Step-by-step explanation:
Step-by-step explanation:
The slope-intercept form can be obtained by solving for y.
8x-y=-6
-8x
-y=-8x-6
divide by negative 1 to turn y positive.
y=8x+6
Answer:
Step-by-step explanation:
(0, 3) (5, 1)
(1-3)/(5-0) = -2/5 is the slope
3 is 95 and 4 is 85. I believe
