What is the point slope form of the line with slope −14 that passes through the point (−2, 9)?

y - 9 = -14 (x + 2)

Step-by-step explanation:

Point-slope form --> y - y1 = m ( x - x1)

slope = -14

y1 = 9

x1 = -2

Let's put the values all together:

y - 9 = -14 (x - - 2)

y - 9 = -14 (x + 2) ---> final answer

It's option B.

Step-by-step explanation:

y - 9 = -14(x + 2)

I have attached a picture of the net with the dimensions you will use labeled.  Please see the attached picture.

To find the surface area you will find the area of the 5 shapes shown in the net.  The 4 triangles are congruent (based on the fact that only one dimension is given on the base).  The other shape is the square base.

Use the following 2 expressions in your final expression:
A = 1/2bh and A = bh

SA= 4(0.5 x 3 x 2.24) + (3 x 3); The bold part is the expression.

SA = 22.44 square cm
