Question

Consider the following equation.

4x+5y=11
Step 1 of 2 : Determine the missing coordinate in the ordered pair (−2,?) so that it will satisfy the given equation.

Answer 1

To find the missing y-coordinate for the ordered pair (-2, ?) in the equation 4x + 5y = 11, substitute x = -2 into the equation, solve for y, and find that y = 3.8.

Step-by-step explanation:

To determine the missing y-coordinate for the ordered pair (-2, ?) that satisfies the equation 4x + 5y = 11, follow these steps:

1. Identify the given x-coordinate, which is -2.
2. Substitute x = -2 into the equation, resulting in 4(-2) + 5y = 11.
3. Simplify the equation to -8 + 5y = 11.
4. Add 8 to both sides of the equation, getting 5y = 19.
5. Divide both sides by 5 to solve for y, giving y = 19/5 or y = 3.8.

Therefore, the missing y-coordinate for the ordered pair is 3.8.
