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)

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
