What determines if a slope is positive or negative?
A higher positive slope means a steeper upward tilt to the curve, which you can see at higher output levels. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line. A slope of zero is a horizontal line.
What can be said regarding a line if its slope is positive negative and zero?
So, The line is parallel to x – axis.
What can be said regarding a line if its slope is?
If the slope of a line is zero, then the line is either the x-axis itself or it is parallel to the x-axis.
What is a slope that is not positive or negative?
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).
How can you tell if a line has a negative slope?
A line with a negative slope is a line that is trending downward from left to right. In other words, the line’s rise to run ratio is a negative value. In this image, the car is driving down a hill that has a negative slope. Notice that the hill is moving downward from left to right.
What can we say if the slope of a line is negative?
A line with a negative slope is a line that is trending downward from left to right. In other words, the line’s rise to run ratio is a negative value.
What can be said about the inclination of a line having slope is not defined II positive?
⇒θ is obtuse. We know that a vertical line is the only line whose slope is not defined. And, the inclination of a vertical line is 90∘. Hence, the inclination of a line whose slope is not defined, is 90∘.
What is positive slope and negative slope?
A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line. A slope of zero is a horizontal flat line.
What does a negative slope tell you about a line?
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
How do you know if a slope is positive or negative?
Well, the slope itself will be negative or positive. You can also look at the graph itself if it is available: if read from left to right and the graphed line ascends (rises), then slope is positive. If the line descends, it is negative. If it is horizontal it has zero slope, and if it’s vertical the slope is undefined.
What is the difference between a positive and negative slope?
If you mean the slope the way that it’s represented on a graph, then you can easily tell the difference because a negative slope will angle downwards (from left to right) and a positive will point toward the top right corner. In numeric form, however, the only real difference is the value of the number.
What is a line with a positive slope?
A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
