Solution

The equation given is 4x+2y=84x + 2y = 8. We need to find solutions for this equation in terms of pairs (x,y)(x, y) and complete the table.

Step-by-Step Solution:

  1. Solve for yy: We can rearrange the equation to solve for yy in terms of xx. 4x+2y=84x + 2y = 8 Subtract 4x4x from both sides: 2y=84x2y = 8 - 4x Divide by 2: y=42xy = 4 - 2x

  2. Complete the Table:

    Now, use this equation y=42xy = 4 - 2x to find values of yy for given values of xx:

    • When x=0x = 0: y=42(0)=4y = 4 - 2(0) = 4 So, the point is (0,4)(0, 4).

    • When x=1x = 1: y=42(1)=2y = 4 - 2(1) = 2 So, the point is (1,2)(1, 2).

    • When x=2x = 2: y=42(2)=0y = 4 - 2(2) = 0 So, the point is (2,0)(2, 0).

Thus, the solution set includes points (0,4)(0, 4), (1,2)(1, 2), and (2,0)(2, 0), which you can plot on the graph.

Final Answer:

The set of solutions is: {(0,4),(1,2),(2,0)}\{(0, 4), (1, 2), (2, 0)\}
