Question

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

Answer 1

Answer:

The graphs in the attached figure

Step-by-step 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
