The whole number x can be written as x/1.
whole number, natural number. integer,rational, and real number
Yes. Suppose the point is P = (x, y). Its reflection, in the x-axis is Q = (x, -y) and then |PQ| = 2y.
if its algebra, x+x ( if you ad two of the same numbers, the answer is always even 1+1 =2 2+2=4 ...etc) Y x2 (multiplying a number by 2 is exactally the same as the previous x+x ) Z x10 (any whole number (not decimal) timed by 10 is always even....)
The only difference is that when a slope is expressed as a whole number, ∆x (changes in x-coordinates) is always one unit.For example,m = 3 = 3/1 = ∆y/∆xm = -1/5 = ∆y/∆xm = 7/6 = ∆y/∆x
