Answer:
y= -x
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Slope
Substitute m= -1 into the equation:
y= -1x +c
y= -x +c
To find the value of c, substitute a pair of coordinates.
When x= -7, y= 7,
7= -(-7) +c
7= 7 +c
c= 7 -7
c= 0
Thus, the equation of the line is y= -x.
Answer:
y=-x
Step-by-step explanation:
Slope =1
Substitute m= -1 into the equation:
y= -1x +c
y= -x +c
To find the value of c, substitute a pair of coordinates.
When x= -7, y= 7,
7= -(-7) +c
7= 7 +c
c= 7 -7
c= 0
Thus, the equation of the line is y= -x.

Answer:
Book Store
Step-by-step explanation:
Find the unit rates by dividing the price by the number of books
Store:
price/books
13.12/2=6.56
$6.56 per book

price/books
46.48/7=6.64
$6.64 per book
So, the book store has the lowest price
