If y=11x−15
, what is the value of y
 when x=(−6)
?

To find the value of \( y \) when \( x = -6 \) in the equation \( y = 11x - 15 \), substitute \( x = -6 \) into the equation:

\[
y = 11(-6) - 15
\]

Now, calculate the result:

\[
y = -66 - 15 = -81
\]

So, the value of \( y \) when \( x = -6 \) is \( y = -81 \).

Would you like further details on how this was solved? Here are five related questions:

1. What is the value of \( y \) when \( x = 0 \) in the same equation?
2. How does the slope of the line affect the values of \( y \) for different \( x \) values?
3. What is the interpretation of the \( y \)-intercept in this equation?
4. How would you graph the equation \( y = 11x - 15 \)?
5. What is the effect on \( y \) if \( x \) increases by 1 unit?

**Tip:** Always double-check your arithmetic when substituting values to ensure accuracy in your calculations.
