Slope Formula And Rate Of Change

The slope of a line represents the steepness or incline of the line. In this case, since the correct answer is "It is negative," it means that the line is sloping downwards from left to right. This indicates that as the x-values increase, the corresponding y-values decrease.

The slope of a vertical line is undefined because a vertical line is perfectly vertical and does not have any horizontal change. In other words, the line does not have a defined rise over run, which is the basis for calculating slope. Therefore, the slope of a vertical line cannot be determined.

The best description of the slope of a horizontal line is that it is 0. This is because a horizontal line has a constant y-coordinate and does not change in the x-direction. Therefore, there is no change in the y-coordinate for any change in the x-coordinate, resulting in a slope of 0.

The slope of a line passing through two points can be found using the formula: slope = (y2 - y1) / (x2 - x1). In this case, the coordinates of the first point are (-3, -2) and the coordinates of the second point are (5, 4). Plugging these values into the formula, we get (4 - (-2)) / (5 - (-3)) = 6 / 8 = 3/4. Therefore, the slope of the line passing through these two points is 3/4.

The slope of a line is calculated using the formula (change in y)/(change in x). In this case, the y-coordinates of both points are the same, which means there is no change in y. Therefore, the slope is 0.

The slope of a line represents the rate of change between any two points on the line. In this case, the slope is -2. This means that for every 1 unit increase in the x-direction, the y-coordinate decreases by 2 units. Similarly, for every 1 unit decrease in the x-direction, the y-coordinate increases by 2 units. The negative sign indicates that the line is sloping downwards from left to right.

The slope of a line can be found using the formula (change in y) / (change in x). In this case, we can choose any two points to calculate the slope. Let's choose the points (4,4) and (6,7). The change in y is 7-4 = 3, and the change in x is 6-4 = 2. Therefore, the slope is 3/2.

In class we have changed this to standard form then done the cover up method to find the intercepts.
