What is the Direct Variation Equation?

Front

What does it mean when we say 'Y varies directly with X'?

Back

It means that as X increases or decreases, Y increases or decreases proportionally.

If Y is 84 when X is 16, how do you find the constant of variation (k)?

What is the equation representing the direct variation of width and length of a rectangle if width is 6 when length is 24?

Back

Front

Back

No, because it includes a constant term (1) which means it does not pass through the origin.

How do you determine if a relationship is a direct variation?

If Y varies directly with X and Y = 10 when X = 2, what is the equation?

What is the graphical representation of direct variation?

Back

The graph of a direct variation is a straight line that passes through the origin.

Front

What happens to Y if X is doubled in a direct variation?

Back

If X is doubled, Y will also double, maintaining the constant ratio k.
