Answer:
B (-9,−57/8)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation
we have

<u><em>Verify each case</em></u>
Substitute the value of x and the value of y in the linear equation and then compare the results
case A) (6,17/2)
For x=6, y=17/2
Substitute

-----> is not true
therefore
The ordered pair not satisfy the equation
case B) (-9,-57/8)
For x=-9, y=-57/8
Substitute

-----> is true
therefore
The ordered pair satisfy the equation
case C) (6,-39/8)
For x=6, y=-39/8
Substitute

-----> is not true
therefore
The ordered pair not satisfy the equation
case D) (6,-8)
For x=6, y=-8
Substitute

-----> is not true
therefore
The ordered pair not satisfy the equation
Answer:
Total 156 people were surveyed.
Step-by-step explanation:
We are given the following in the question:
A survey was conducted about favorite book categories.
Out of which one fourth of total number of people surveyed or 39 people responded that mystery was their favorite category.
