No. Direct variation describes a relationship between two variables. It has nothing to do with the value of a single number.
No, it does not.
No, y+2=x does not show direct variation. In direction variation you need to be able to multiply y by something to get x. In the question y+2=x, you have to add 2 to y to get x, which is not multiplying.)
Yes. y = 1x is the same as y = x which is the simplest case of direct variation. If you consider the equation y = mx + b, then a direct variation will always have b = 0 (i.e. the graph goes through the origin). The value of m is called the "constant of variation", and the equation is usually written as y = kx.
1 = 4/4 - 3/4 = 1/4

The scale of a map is decreased to show the representation of actual miles to the distance found on a map. If three fourths of an inch on a map was equal to 750 miles, an inch on the maps scale would equal 1,000 miles.

Variations arise due to recombinations(gene rearrangements) ,mutations etc.The former is the principal source of variation in sexually reproducing organisms and the latter is the source of variation in asexual organisms.According to Darwin variation arises due to chance since all the above mentioned process occur in nature spontanuously all organisms show variation
