(b)

Concept Used:

  • The slope of a line is defined as rise over run

Calculation:

In order to find the greater slope of the line, in the given graph y-axis is -35 to 35, so in the first (a) graph the slope is 3520 because from 0,0 it rise 35 units and then run 20 units to the right top corner, so slope of a line in (a) is 3520 or 1.7

Now in graph (b) y-axis is -20 to 20, so in graph (b) slope is 205 , because from 0,0 it rises 20 units and then run 5 units to the right top corner , so the slope of line (b) is 205 or 4

So, graph (b) has greater slope.
