Line 1
Points : (8,-4) and (2,-5)
To find the slope:
M = (y - y) / (x - x)
M = (-4 - -5) / (8 - 2)
M = (-4 + 5) / 6
M = 1 / 6 (answer)
Line 2
Points: (10, 9) and (15, -21)
M = (y - y) / (x - x)
M = (9 + 21) / (10 - 15)
M = 30 / -5
M = -30/5 (reduce this)
M= -6 (answer)
One equation that could be used would be t = 25-12
The volume of a cuboid is = length × width × height.
Let the width of Olivia's lunch box be 'x'.
Hence the length of Olivia's lunch box shall be 'x + 2'
Also the height of the box is given as 3 inches.
The volume of the box is 240 in³
Substituting in the formula we get

Dividing by 3 on both sides

Exapnding we get

Subtracting 80 from both sides

Factoring

We get
x= -10 or x = 8
But x cannot be negative
So x = 8
Hence the width of the box is 8 inches.
