Never.
Write the equation of the line in the standrad form: y = mx + c The slope of this line is m The inverse of the slope is then 1/m. Note, that for a line perpendicular to the first, you need the negative inverse, not just the inverse. And the negative inverse of m is -1/m.
1. The slope of a flat line is smaller than the slope of a steep line.2. The slope of a flat line should be close to 0. 3. A negative slope means that the line mover down from left to right.
Not always because it can also be negative

False.
A direct relationship if the slope of the line is positive. An inverse relationship if the slope of the line is negative.
If a line has a slope m then a line perpendicular to it has a slope -1/m ( negative inverse). For example if a line has slope positive 2, its perpendicular has slope -1/2

No because the slope of a line can be positive or negative
The line has a negative slope (or negative gradient).When the angle between the line and the positive direction of Ox is obtuse then the slope is negative. Conversely, when the angle is acute, the slope is positive.
If two variables have a negative linear correlation, the slope of the least-squares regression line is negative. This indicates that as one variable increases, the other variable tends to decrease. Thus, the negative slope reflects the inverse relationship between the two variables.
You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. 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.
If a line has a negative slope it is going 'down hill' and if it has a positive slope it is going 'up hill'
No, a line with a positive slope and a line with a negative slope cannot be parallel. Parallel lines have the same slope, meaning they rise or fall at the same rate. A positive slope indicates that a line rises as it moves from left to right, while a negative slope indicates that a line falls. Therefore, these two types of lines will eventually intersect if extended far enough, demonstrating that they are not parallel.
To determine if a slope is negative or positive, you can look at the direction of the line on a graph. If the line rises from left to right, the slope is positive; if it falls from left to right, the slope is negative. Mathematically, if the change in y (vertical) over the change in x (horizontal) is greater than zero, the slope is positive, while a value less than zero indicates a negative slope.
A line does not have an inverse!
The answer depends on the signs of the original intercepts.x negative, y negative: negative slope becomes less negative and could go positive.x negative, y positive: positive slope becomes greater.x positive, y negative: positive slope becomes less positive and could go negative.x positive, y positive: negative slope becomes more negative.For 1 and 3, the slope changes sign when the y intercept crosses the origin.
