Question

Determine the missing coordinate in the ordered pair (?,-3)so that it will satisfy the given equation

Answer 1

Given equation:

`2x-3y=4`

To find the missing coordinate:

Substitute the -3 for y in the equation above and solve for x:

`\begin{gathered} 2x-3(-3)=4 \\ 2x+9=4 \\ 2x=4-9 \\ 2x=-5 \\ x=-(5)/(2) \end{gathered}`

The missing coordinate is:

`-(5)/(2)`
