Determine whether the lines are parallel. use slope to explain your answer. use the graph shown below. the slope is of the red line is the slope is of the blue line is the lines do/do not have the same slope so they are/are not parallel. it's my third time trying to figure it out!

red  1/2,

blue  2/5  

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

Step-by-step explanation:

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

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

  We have the points (0,1) and (2,2)

m= (2-1)/ (2-0)

  = 1/2

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

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

  We have the points (0,-5) and (5,-3)

m= (-3--5)/ (5-0)

  = (-3+5)/(5-0)

  = 2/5

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

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180
