Y = m x + b
  2 = 6 m + b
-4 = 8 m + b   /*(-1 )
---------------------------
 2 = 6 m + b
+
 4 = - 8 m - b
--------------------
6 = - 2 m
m = - 3
2 = 6 * ( - 3 ) + b
2 = - 18 + b
b = 20
The equation is:
y = - 3 x + 20           ( or in the other form: 3 x + y - 20 = 0 )

Complete this table showing the number of shaded triangles in each step and area of each triangle!
djverab [1.8K]

Answer:

Step-by-step explanation:

From the table attached we find,

Number of shaded triangles = 1

Area of each shaded triangle = 256 square inches

Now we can complete the table following the same pattern,

Step number     Number of shaded triangles   Area of the shaded triangles

        0                                   1                                                   256

        1                                    3                                  256 × 3 = 768

        2                                   5                                256 × 5 = 1280

        3                                   7                                  256 × 7 = 1792

D. 2 x 2 x 2 x 2 x 2 x 3 x 3= 4*4*6*3=16*18= 288

Answer is C. -2 x 2 x 2 x 2 x 2 x 3 : 96 ( not D. = 298 , 298 is greater than 96)
