Some students compared the two graphs. Which statement is correct? (click to enlarge the image)

• both lines have the same slope because they are both green

• both lines have the same slope because they both slant the same way

• both lines have the same slope because the lines are the same length

• both lines have different slopes because the graphs are scaled differently (axis labels/intervals are different)
