Chapter 9, Problem 7PFA

To determine

To select correct option representing the solution set.

Answer to Problem 7PFA

Option A. $-\frac{1}{3}x<1$

Explanation of Solution

Given information :

Solution set graphed is $x>-3$

Option A. $-\frac{1}{3}x<1$

Option B. $-\frac{1}{3}x>1$

Option C. $-\frac{1}{3}x<-1$

Option D. $-\frac{1}{3}x>-1$

:

Option A. $-\frac{1}{3}x<1$

Then above expression can also be written as $x>-3$

Option B. $-\frac{1}{3}x>1$

Then above expression can also be written as $x<-3$

Option C. $-\frac{1}{3}x<-1$

Then above expression can also be written as $x>3$

Option D. $-\frac{1}{3}x>-1$

Then above expression can also be written as $x<3$

Among all the options, option A can be rewritten to get the actual expression representing the graph that has been plotted.
