Answer:
The equation which has the steepest graph is:
Option: A
A.

Explanation:
We know that the slope-intercept form of a line is given by:

where m is the slope of the line and c is the y-intercept of a line.
- If the absolute value of the slope is greatest then that line is most steep.
A)

The slope is: 11
B)

The slope is:

C)

The slope is: 7
D)

The slope of this line is: 3
The line which has the largest absolute value of slope is:

Hence, the graph of this equation will be steepest.
