A rectangular piece of metal is 8 in. longer than it is wide. Squares with sides 3 in. long are cut from the four corners, and 
the flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 76 in. cubed?

Answer:
Let the width be = w 
The length will be = w+8
And height = 3 inches
Volume = l x w x h

=> 
=> 
=> 
Solving this we get w = 2.43 inch or w = -10.43 inch
Neglecting the negative value, we get w = 2.43 inches.
And l= inches
 inches

y = -2x + 6
Steps:
y = mx + b
m is slope
b is the y-intercept
m = -2
b = 6
plug in m and b
y = -2x + 6
