Find the slope 1) (6,3) (6,-1) 2: (9,-3) (-2,3) 3: y=-9x-1 4: -2y=x-1 5: 3x-5y=7

Finding the slope from two points is as simple as:

Plug in your quantities:

because, y2 = -1, y1 = 3, x2 = 6, x1 = 6

Solve:

This is as far as this equation goes because you cannot divide by zero - are you sure you've provided the correct equation?

223cm

Step-by-step explanation:

First you want to figure out how many faces the 3D shape has.

This has 5 faces.

Then you find the area of each face.

The front face has an area of 54cm because the length is 6cm and the width is 9cm.

Area = Length x Width

The back face will always have the same area as the front.

54cm + 54cm = 108cm (Front and Back Face)

Now the right side and left side.

The width of the side is 5cm and length is 7cm.

7cm • 5cm = 35cm

Just like the front and back, the right and left side will have the same area.

35cm + 35cm = 70cm

Now the last part.

There is no top face since this is a 3D triangle and not a square and rectangle etc.

So, you don't add it two times like the others.

The bottom's width is 5cm and the length is 9cm

5cm • 9cm = 45cm

Now you add all of it up together to find the surface area.

108cm + 70cm + 45cm = 223cm
