Final answer:
To find the missing y value when x is 4, substitute into y = -2x + 4 to get y = -4. For the missing x value when y is 2, rearrange the equation to solve for x, resulting in x = 1. Thus, the completed ordered pairs are (4, -4) and (1, 2).
Step-by-step explanation:
To compute the missing x and y values so that each ordered pair will satisfy the given equation y = -2x + 4, we need to substitute the given values for x and y into the equation and solve for the unknown variable. For the ordered pair with y unspecified (denoted as 4y), we substitute x with 4 into the equation, giving us y = -2(4) + 4. Simplifying this, we get y = -8 + 4, which results in y = -4.
For the ordered pair with x unspecified (denoted as x2), we substitute y with 2 into the equation, and then solve for x: 2 = -2x + 4. By rearranging the equation, 2x = 4 - 2, we get 2x = 2, and dividing both sides by 2 yield x = 1. Therefore, the missing value for x is 1.
In summary, the missing values for the ordered pairs are (4, -4) and (1, 2).
