Lets plug in the solutions and see if it works.

Or you can graph it using Desmos Graphing Calculator and see what points fall in the shaded area.

TheSmartOne (thesmartone):

Lets plug in (0,-9) 4(0)+(-9)>-6 0-9>-6 -9>-6 is false a is not a solution

TheSmartOne (thesmartone):

lets plug in (-3,6) 4(-3)+(6).-6 -12+6>-6 -6>-6 is also false So b is not a solution either

TheSmartOne (thesmartone):

lets plug in (-1,-1) 4(-1)+(-1)>-6 -4+1>-6 -3>-6 is true This is a solution

TheSmartOne (thesmartone):

Lets just make sure the others are not solutions either

TheSmartOne (thesmartone):

So lets plug in (2,0) 4(2)+(0)>-6 8+0>-6 8>-6 This is also a solution

TheSmartOne (thesmartone):

Finally lets plug in (4,-20) 4(4)+(-20)>-6 16-20>-6 -4>-6 Also a solution

TheSmartOne (thesmartone):

So we have three solutions (4,-20) (2,0) (-1,-1)
