Provide an appropriate response.y = xy = -xy = -3xGraph the set of equations on the same grid. Compare the slopes, y-intercepts, and their effects on the graphs.
What will be an ideal response?
Answers may vary. One possibility:
| y = -3x |
For y = x, the slope is 1; for y = -x, the slope is -1; for y = -3x, the slope is -3. The first two lines are equally steep. The third line is steeper, since the absolute value of its slope is greater than the absolute value of the slope of either of the other lines. Since the first line has a positive slope, it goes uphill from left to right. Since the other two lines have a negative slope, they go downhill from left to right. The y-intercept of all three lines is the origin, (0, 0).
