To solve for a, you must get a by itself on one side of the equation. Now, a is "joined" to m by multiplication. To "separate" them, use the inverse operation, division.
Divide both sides of the equation by m.
Divide both sides of the equation by m.
Given inequality is:
Now for (6,-4), Put x=6 nd y=-4 in given inequality:
So for (6,-4) this inequality is true.
For (-2,-3) put x=-2 and y=-3 in given inequality:
As -32 is less than -8 then this condition is also true.
simillarly you can check for other options also.
For (-7,5) Put x=-7 and y=5 in given inequality:
As 12 is grater than -8 so this condition is false.
And for (-6,0) put x=-6 and y=0 in given inequality:
As -24 is less than -8 so it is true.
