Answer 2

Graph of the Proportional Relationship y = -3x

To plot the graph of the proportional relationship y = -3x, we can use a coordinate plane. The x-axis represents the input values (x) and the y-axis represents the corresponding output values (y).

To get started, let's choose some values for x and calculate the corresponding values for y using the equation y = -3x. We can then plot these points on the graph.

Let's choose x = -2, -1, 0, 1, and 2:

When x = -2: y = -3(-2) = 6 So, the point (-2, 6) is on the graph.

When x = -1: y = -3(-1) = 3 So, the point (-1, 3) is on the graph.

When x = 0: y = -3(0) = 0 So, the point (0, 0) is on the graph.

When x = 1: y = -3(1) = -3 So, the point (1, -3) is on the graph.

When x = 2: y = -3(2) = -6 So, the point (2, -6) is on the graph.

Now, let's plot these points on the graph:


As you can see, the graph is a straight line that passes through the points (-2, 6), (-1, 3), (0, 0), (1, -3), and (2, -6). The line has a negative slope of -3, which means that as x increases, y decreases proportionally.

I hope this helps! Let me know if you have any further questions.
