Question

what is indirect variation

Answer 1

Direct variation is given by an equation,

\(\LARGE\color{black}{ y=k\times x }\)

Where k is a (reaL) number, (not a variable).

Answer 2

Indirect variation is similar

\(\LARGE\color{black}{ y=(k\times x) +b }\)

(where b and k are numbers, that can be the same, but not necessarily the same)

Answer 3

Basically,

Direct variation,
\(\LARGE\color{black}{ y=mx+b }\) when b=0.

Indirect variation,
\(\LARGE\color{black}{ y=mx+b }\) when b≠0

Answer 4

(Ooops, refresh please)

Answer 5

Any line that goes through (0,0) is a (graph of a) direct variation,
and any line that doesn't go through (0,0) (i other words, it has non-zero x and y intercepts) that is a (graph of an) indirect variation.
