Why is the slope -3 steeper than the slope 2?
The number shows how steep it is, the sign is whether it is going up or coming down. So 2 is a slope upwards and -3 is a steeper slope down
What are the properties of a slope?
The slope is the ratio of the vertical increase divided by the horizontal increase. The slope of a flat line is 0. The slope of a flatter line is smaller than the slope of a steeper line. A positive slop indicates that the line move up from left to right. A negative slope means that the line moves down from left to right.
Why is zero neither posotive or negative?
The easiest way to see it is: Positive means greater than zero Negative means less than zero So zero is neither of these.
Can two lines with a negative slope be perpendicular?
NoIf the slope of a given line is x, than the slope of the line perpendicular to the first line is 1/-x. So if the first slope is negative, the second will be positive, and vice versa.
Does a negative line have a different slope than a positive one?
Yes. If the fraction is the same, the negative slope would have at least one negative number, while the positive would have both positive numbers. I'm pretty sure. :)
