For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive.

WebI recommend that when you talk about slopes, you just describe them in terms of steepness and whether they're positive or negative: The graph of y=-3x has a steeper negative slope than that of y=-.5x The graph of y=-3x has a steeper slope than y=x, but the former is decreasing while the latter is increasing. WebYou can calculate the slope from the x- and y-intercepts. But in this case, we can't tell exactly what the x-intercept is just from looking at the graph - we can only see that it is somewhere between 6 and 7. In order to …
WebNegative Slope. A negative slope refers to a line that is trending downwards as it moves from left to right. The rise to run ratio of a line with a negative slope is negative. It can be calculated using the formula m = (y 2 - y 1)/(x 2 - x 1) = Tan θ = f'(x) = dy/dx.The negative slope signifies that, if one quantity is decreasing another quantity is increasing.
