Write an inequality for the graph.
A) -6x+5y>=-30
B)-6x+5y<=-30
C)5x-6y<=-30
D)5x-6y>=-30

Use y = mx + b to determine the equation of the graph, then decided the inequality symbol.
m = +5/+6 = [tex]\frac{5}{6}[/tex] b = 5
y = [tex]\frac{5}{6}[/tex]x + 5
6y = 5x + 30
-30 = 5x - 6y ⇒ 5x - 6y = -30
Now let's look at the inequality symbol: The shaded area is below so it will be a less than symbol and it is a solid line so the equal sign is included.
Answer: 5x - 6y ≤ -30
Answer: 5x-6y >= -30
Step-by-step explanation:
Pick two points from the graph to frame the equation of the line = (0,5) and (-6,0)
Frame the equation y=mx+b, where m is the slope and b is the y-intercept
The y-intercept is the point where the graph crosses y-axis and it is equal to 5.
slope m = y2-y1/x2-x1 = 0-5/-6-0 = 5/6
Equation becomes y = 5/6x+5
Multiply the whole equation by 6
6y+5x = 30
Subtract 5x on both sides
-5x+6y = 30
Multiply whole equation by -1
5x-6y = -30
Now we look at the shaded part and confirm the inequality
The shaded part contains (0,0)
So we plug in 0 for x and 0 for y
5(0) - 6(0) = -30
0 >= -30 is true
So inequality becomes 5x-6y >= -30
