We have the next inequality

-3y< 6x-18

We need to isolate the y because the y is multiplying a negative number the sense of the inequality will change


y>(6x-18)/(-3)

we simplify and we solve the inequality for y


y>-2x+6

Let's calculate now some points of the boundary line

the boundary line is


y=-2x+6

If x=-2

y=-2(-2)+6=4+6=10

Point (-2,10)

If x=0

y=-2(0)+6=6

Point (0,6)

if x=2

t=-2(2)+6=-4+6=2

Point (2,2)

Then the boundary line will be a dashed line because we have a a sign greater than and the solution area will be above this boundary line

Therefore the graph of this inequality

Solve the inequality for y, and identify the graph for the solution. -3y< 6x-18-example-1
