Which graphs show functions with direct variation? check all that apply.

Direct variation is a simple relationship between two variables either.

If we call x and y to these variables, then:

'y' varies directly with x. If x increases 'y' it also increases, if x decreases 'y' decreases.

This relationship can be represented in the following way:

y = mx.

Where m is the rate of change, called "constate of variation" and is also the slope of the line.

Note that when x and y vary directly, the equation of the line always passes through the origin.

Therefore to correctly answer this question look for all the lines that pass through the point (0,0)

think about it deeply and passionately about this property
