Given the equation y=-3x+2.5, answer the following:

Part A: When x is 1, what value of y makes the equation true?

To find the value of \( y \) when \( x = 1 \), substitute \( x = 1 \) into the equation \( y = -3x + 2.5 \):

\[
y = -3(1) + 2.5 = -3 + 2.5 = -0.5
\]

So, when \( x = 1 \), \( y = -0.5 \).

Would you like more details or further clarification? 

Here are 5 related questions:

1. What happens to the value of \( y \) as \( x \) increases?
2. How would the equation change if the slope were positive?
3. What is the slope of the line represented by this equation?
4. At what value of \( x \) does \( y \) equal 0?
5. Can you graph this equation and identify its intercepts?

**Tip:** The slope of a line tells you how steep it is; in this case, a slope of -3 indicates the line is decreasing as \( x \) increases.
