In an inequality we describe the real distance. for example 3+4+x>7 or equal to7.
in an equation we describe the distance it self at a given point for example 3x+1=10
x=3.
so an equation is specific, and inequality is not
An ratio is a fraction that describes a comparison of two numbers or quanitites
The answer would either be y-6 = -3(x+2) or y = -3x
You can find that out by using your calculator. It will be glad to let you know. You can put it in like this.
4
÷
5

Your calculator will come back with 0.8
So now you need only add on the 2
2 + 0.8 = 2.8 <<<<< Answer
1 is a rational number
2 is a natural, whole, and rational number
3 is a natural, whole, and rational number
4 is rational
