Answer 2

Graph of the Function y = -3x

To graph the function y = -3x, we can plot several points and connect them to form a straight line. The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -3, which means that for every increase of 1 in the x-coordinate, the y-coordinate decreases by 3.

Let's plot a few points to create the graph:

When x = 0, y = -3(0) = 0. So we have the point (0, 0). When x = 1, y = -3(1) = -3. So we have the point (1, -3). When x = -1, y = -3(-1) = 3. So we have the point (-1, 3).

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

The points (0, 0), (1, -3), and (-1, 3) lie on the line. We can now connect these points to form a straight line:

The line represents the graph of the function y = -3x. It has a negative slope, which means it slopes downward from left to right. As x increases, y decreases.

Conclusion

The graph of the function y = -3x is a straight line with a negative slope. It passes through the points (0, 0), (1, -3), and (-1, 3). As x increases, y decreases.
