M = y2-y1 / x2-x1
= 2-1 / 1-2
= 1 / -1
= -1
Answer:
216 cm^2
Step-by-step explanation:
A cube has 6 congruent, square faces.
Each face has side length of 6 cm.
The total surface area is the sum of the surface areas of the 6 faces, but since all faces are congruent, the total surface area is
SA = 6s^2
where s = side length
SA = 6 * (6 cm)^2
SA = 6 * 36 cm^2
SA = 216 cm^2
You need to simplify it first.

Use distribution

y=mx+b
m=slope
your slope is -4 :)
