Y=4x−9<br> Complete the missing value in the solution to the equation
weeeeeb [17]

Answer:

<h2>The missing value is 3, and the coordinates are (3,3).</h2>

Step-by-step explanation:

The complete question is

y=4x-9

Complete the missing value in the solution to the equation. (3, ? )

By given, we know that x=3, because coordinates are written like (x,y).

Then, we replace the given coordinate to find y.

y=4x-9\\y=4(3)-9\\y=12-9\\y=3

Therefore, the missing value is 3, and the coordinates are (3,3).
