Question

y=2x+3 , determine if the equation shows a direct variation between x and y ,give the constant m of the direct variation.

Answer 1

The constant of variation is the same as the slope - 2.

Answer 2

why negative though?

Answer 3

sorry, thats a dash not a negative

Answer 4

ohh ok thanks, also is the direct variation always m ?

Answer 5

yup, the coefficient of the x for all linear equations is also the direct variation
