Question

Tell whether the equation represents a direct variation. If so identify the constant of variation.

y = 2x - 9

Answer 1

2 i think..

Answer 2

2 = m, which is the variable i think

Answer 3

wait. 2 is not the variable. it's a co-efficent.

Answer 4

the constant

Answer 5

well by varaible i meant constant i guess, it's the slope to which y and x will vary to each other.

i dont think the y-intercept will have any effect on the matter..

Answer 6

i think im wrong actually, because with direct variation it always has to go through the point (0,0) so the y-intercept is actually KEY to the whole matter lol

Answer 7

direct variation means y=kx
in your question it isn't
