Graph Y against 1/X

Directly proportional

Curve graph

Inversely proportional

The graph never touch the Y and X-axis

Inversely proportional graph

Graph start at (0,0)

Graph, Y is directly proportional to X

Same graph but different axis

y is inversely proportional to x and y is directly proportional to x

Y-axis will never be zero, and X-axis will never be negative values

y decreases linearly with x

Y and X axis will never be zero

y increases linearly with x

This graph is not straight line

y is inversely proportional to x

This graph have two gradient

y is inversely proportional to x

The difference between graph y increases linearly with x and graph y decreases linearly with x

The gradient
