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 5 right parenthesis, and left parenthesis 2 comma 10 right parenthesis.

The correct graph for the proportional relationship y=-2x by plotting points is:
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 ends joins three plotted points and extends beyond. The coordinates of the plotted points are: (0, 0), (1, -2), and (2, -4).

To graph the proportional relationship y = -2x by plotting points, you can follow these steps:
1. Start by creating a coordinate plane. In this case, the x-axis ranges from -9 to 9 in unit increments, and the y-axis ranges from 11 to -11 in unit increments.
2. Plot three points on the coordinate plane that satisfy the equation y = -2x. To do this, substitute different x values into the equation and solve for y. The points should have coordinates (x, y).
- The first point is (0, 0), as substituting x = 0 into the equation gives y = -2(0) = 0.
- The second point is (1, 5), as substituting x = 1 into the equation gives y = -2(1) = -2.
- The third point is (2, 10), as substituting x = 2 into the equation gives y = -2(2) = -4.
3. Once you have plotted these three points, draw a line through the points that extends beyond them on both ends. The line should be straight and pass through all three points.
The correct answer, as described above, is the image that shows the coordinate plane ranging from -9 to 9 on the x-axis and from 11 to -11 on the y-axis. The points plotted on the graph are (0, 0), (1, 5), and (2, 10), and a line is drawn through these points with arrows at both ends.
