What else can I help you with?
Lines always have a slope of zero.?
Horizontal lines always have a slope of zero. (i.e completely flat, level surfaces have a slope of zero). However a line does not have to have a slope of zero in order to be a line.
Do rising lines always have negative slopes?
If a line on a graph is rising as it goes from left to right, it has a positive slope. If it is falling from left to right (or rising from right to left) it has a negative slope. If it is horizontal, it has a slope of zero.
Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
How do you tell if a slope is negative or positive?
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.
When a pair of variables have a positive correlation will the slope in the regression equation always be positive?
Yes
What slope do horizontal lines always have?
Horizontal lines always have a slope of 0.
Do horizontal lines always have a slope of zero?
Yes. There is no positive or negative rise to generate a slope, and it cannot have a run of zero length.

Horizontal lines always have a slope of zero. (i.e completely flat, level surfaces have a slope of zero). However a line does not have to have a slope of zero in order to be a line.
Do rising lines always have negative slopes?
If a line on a graph is rising as it goes from left to right, it has a positive slope. If it is falling from left to right (or rising from right to left) it has a negative slope. If it is horizontal, it has a slope of zero.
Is a slope of a line always positive?
No because the slope of a line can be positive or negative
Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
The slope of a horizontal line is?
Horizontal lines have a slope of 0.
Is the slope always positive if the coordinates of two points on the line are positive?
No.
The slope of a line is always positive?
Not always because it can also be negative
Slope of horizontal line?
The slope of a horizontal line is zero.
Define the 4 types of slopes?
undefined, zero, negative, and positive are the 4 types of slopes
What is slope of velocity v time graph?
The slope of a velocity vs. time graph represents acceleration. A positive slope indicates acceleration in the positive direction, a negative slope indicates acceleration in the negative direction, and a horizontal line indicates constant velocity.
