To write the equation of the line use the point slope form. Then convert to the standard from. Begin by substituting m = -1 and (-2,6).

$y - y_1 = m(x-x_1)\\y - 6 = -1(x --2)\\y - 6 = -1(x+2)\\y - 6 = -x -2\\x + y - 6 = -2\\x + y = 4$

Gekata [30.6K]

Answer:

69,286,455 cu inches

Step 1: Convert yards to inches

1 cu yard = 46656 cu inches

11 cu yard = y cu inches

y = 11 x 46656

y = 513216 cu inches

Step 2: Find total inches

513216 + 17 = 513233 cu inches

Step 3: Multiply total inches by 135

513233 x 135 = 69,286,455 cu inches
