Question

Determaine whether each equation represents a direct variation if it does find the constant variation
2y=5x+1

Answer 1

Solve 2y=5x+1 for y, so that you can tell more quickly whether or not this is an example of direct variation.

Divide both sides of this equation by 2. Your result?

Answer 2

\[2y \div 2\]

Answer 3

?

Answer 4

I'm sorry if I'm wrong i'm pretty bad at math

Answer 5

\[\frac{ 2y }{ 2 }=\frac{ 5x }{ 2 }+\frac{ 1 }{ 2 }=?\]

Answer 6

2y/2=1

Answer 7

i keep on getting 2/5

Answer 8

for the second 5/2

Answer 9

Note: (2y)/2 is not 1; it is y.

2y
-- = y
2

So you have y=(5/2)x + (1/2).

Example of DIRECT PROPORTION: y=8x

Example of first order function that is NOT direct proportion: y = mx + b, or y=6x - 7.


So, is the given function an example of direct proportion, or NOT an example?
