Question

Consider the following equation.x - 2y = 3Step 1 of 2: Determine the missing coordinate in the ordered pair (-4, ?) so that it will satisfy the given equation.

Answer 1

Answer:

The missing coordinate is;

$\begin{gathered} -\frac{7}{2} \\ (-4,-\frac{7}{2}) \end{gathered}$

Explanation:

Given the equation;

$x-2y=3$

We want to determine the missing coordinate in the ordered pair;

$(-4,_-)$

We can get the value of y by substituting the value of x into the equation;

$\begin{gathered} x-2y=3 \\ -4-2y=3 \\ -2y=3+4 \\ -2y=7 \\ y=-\frac{7}{2} \\ y=-3.5 \end{gathered}$

Therefore, the missing coordinate is;

$\begin{gathered} -\frac{7}{2} \\ (-4,-\frac{7}{2}) \end{gathered}$
