Answer:
Option D. is the correct option.
Explanation:
Since all the given graphs are of a straight line therefore the graph which will have the maximum slope will be the steepest.
Standard equation of a line is y = mx + c
here m is the slope.
A. y = 1/2x +3
m = 1/2
B. y = 3x +144
m = 3
C. y = 7x + 16
m = 7
D. y = 11x - 144
m = 11
therefore Option D. has the maximum slope.
