Answer:

red 2/3

blue 1/2

The lines do not have the same slope so they are not parallel

Explanation:

We can find the slope of the red line by using the formula

m = (y2-y1)/(x2-x1)

We have the points (0,2) and (3,4)

m= (4-2)/ (3-0)

= 2/3



We can find the slope of the blue line by using the formula

m = (y2-y1)/(x2-x1)

We have the points (0,-2) and (4,0)

m= (0--2)/ (4-0)

= (0+2)/(4-0)

= 2/4

=1/2


The lines do not have the same slope so they are not parallel
