Graph the proportional relationship y=−2x
by plotting points.(1 point)
Responses
A coordinate plane ranges from negative 9 to 9 in unit increments on the x-axis and from 11 to negative 11 in unit increments on the y-axis. A line with arrows at both the ends joins three plotted points and extends beyond. The coordinates of the plotted points are: left parenthesis 0 comma 0 right parenthesis, left parenthesis 1 comma 2 right parenthesis, and left parenthesis 2 comma 4 right parenthesis.

To graph the proportional relationship given by the equation \( y = -2x \), we can find a few key points by substituting various values for \( x \):
1. When \( x = 0 \):
\[
y = -2(0) = 0 \quad \Rightarrow \quad (0, 0)
\]
2. When \( x = 1 \):
\[
y = -2(1) = -2 \quad \Rightarrow \quad (1, -2)
\]
3. When \( x = 2 \):
\[
y = -2(2) = -4 \quad \Rightarrow \quad (2, -4)
\]
Now, let's evaluate the plotted points given in the options:
- **Option 1**: (0, 0), (1, 2), (2, 4)
- **Option 2**: (0, 0), (1, -2), (2, -4)
- **Option 3**: (0, 0), (1, 5), (2, 10)
- **Option 4**: (0, 0), (1, -1), (2, -2)
The correct points that match the calculations are \( (0, 0) \), \( (1, -2) \), and \( (2, -4) \). Thus, the correct option is:
**Option 2**: A coordinate plane ranges from negative 9 to 9 in unit increments on the x-axis and from 11 to negative 11 in unit increments on the y-axis. A line with arrows at both the ends joins three plotted points and extends beyond. The coordinates of the plotted points are: \( (0, 0) \), \( (1, -2) \), and \( (2, -4) \).

\[
y = -2(0) = 0 \quad \Rightarrow \quad (0, 0)
