Question 1014801
I will understand your question as asking which linear function has the greatest absolute value of the slope.

The first line has a slope of -5, so the absolute value is 5.
The second line has a slope of 3, from the slope-intercept form.  Its absolute value is 3.
The 3rd line has a slope of -2, and so its absolute value is 2.
The last line has slope of -1, with absolute value 1.

Therefore, the line that has the greatest rate of change is the 1st line, choice A.
