Math Problem Statement

Copy and complete the table for the graph 2x - y = 8.

Solution

To solve this problem and complete the table for the equation 2xy=82x - y = 8, we need to isolate yy in terms of xx and substitute the given values of xx into the equation.


Step 1: Rearrange the equation

The given equation is:
2xy=82x - y = 8 Rearranging for yy, we get:
y=2x8y = 2x - 8


Step 2: Substitute values of xx into y=2x8y = 2x - 8

  1. For x=2x = -2 (A):
    y=2(2)8=48=12y = 2(-2) - 8 = -4 - 8 = -12 So, A=12A = -12.

  2. For x=0x = 0 (B):
    y=2(0)8=08=8y = 2(0) - 8 = 0 - 8 = -8 So, B=8B = -8.

  3. For x=2x = 2 (C):
    y=2(2)8=48=4y = 2(2) - 8 = 4 - 8 = -4 So, C=4C = -4.


Step 3: Complete the table

The completed table is:

xx2-21-1001122
yy12-1210-108-86-64-4

Final Answers:

  • A=12A = -12
  • B=8B = -8
  • C=4C = -4
