Slope of any line is the angle by which any line is inclined to the x axis.Slope is the ratio of rise and run.
Slope = [tex]\frac{Rise}{Run}.[/tex].The vertical change between two points is called the rise, and the horizontal change is called the run.
In the given question Marty's has a slope [tex]\frac{2}{3}[/tex] and Ethan has a slope[tex]\frac{2}{5}[/tex] .
As the slope is positive the line will move up then right.Line with slope .Marty is haveing a greater slope than Ethan.
In second case Marty's slope is[tex]\frac{1}{3}[/tex]and Ethan slope is [tex]\frac{1}{5}[/tex]
Here Marty will have a greater slope.
