Question

Show the graph of each line: y=-2x ; y=1/2x;y=-1/2x;y=2x

Answer 1

The graphs in the attached figure

Explanation:

we have

`y=-2x` ---> equation A

This line represent a proportional relationship with slope equal to m=-2

`y=(1/2)x` ---> equation B

This line represent a proportional relationship with slope equal to m=1/2

`y=-(1/2)x` ---> equation C

This line represent a proportional relationship with slope equal to m=-1/2

`y=2x` ---> equation D

This line represent a proportional relationship with slope equal to m=2

Remember that in a proportional relationship the line passes through the origin
