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.
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.
The slope of the graph of a direct variation is always positive.
Yes
A horizontal line has a slope of zero. The equation of a horizontal line is y = a.
Horizontal lines always have a slope of 0.
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.
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.
No because the slope of a line can be positive or negative
The slope of the graph of a direct variation is always positive.
No.
Horizontal lines have a slope of 0.
Not always because it can also be negative
The slope of a horizontal line is zero.
Positive slope: The line rises from left to right. Negative slope: The line falls from left to right. Zero slope: The line is horizontal. Undefined slope: The line is vertical.
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.
