x−2 has an x-coordinate of 9, what is its y-coordinate?

y=33

y=1

y=9

y=−5

1 answer

To find the y-coordinate of the point on the line given by the equation \( y = \frac{3}{1} x - 2 \) (which simplifies to \( y = 3x - 2 \)), we substitute the x-coordinate of 9 into the equation.

Here's the calculation:

\[ y = 3(9) - 2 \] \[ y = 27 - 2 \] \[ y = 25 \]

None of the answer choices match \( y = 25 \).

There may be a typographical error in the question regarding the equation of the line. If the line were instead \( y = 3x + c \) where \( c \) is a different value, please clarify the correct equation.

However, based on the information provided, the correct y-coordinate for \( x = 9 \) is \( y = 25 \).
