Is a negative slope undefined?
The slope of a line can be positive, negative, zero, or undefined. because division by zero is an undefined operation. Vertical lines are symbolically represented by the equation, x = a where a is the x-intercept.
How do you tell if a slope is positive or negative?
If the line is sloping upward from left to right, so the slope is positive (+). If the line is sloping downward from left to right, so the slope is negative (-). In our pizza example, a positive slope tells us that as the number of toppings we order (x) increases, the total cost of the pizza (y) also increases.
How do you know the difference between a positive and negative slope?
Slopes can be positive or negative. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.
How do you know if a slope is positive negative zero or undefined?
Positive slope means the graph rises or goes uphill. Negative slope means the graph falls or goes downhill. Zero slope means the line is flat or horizontal. Undefined slope means the line is vertical.
What can be said regarding if a line if its slope is negative θ is an obtuse angle?
Hence, we can say that the line with zero as the slope is parallel to the x-axis. Hence, we can say that the line with negative slope makes an obtuse angle with the x-axis when measured anti-clockwise.
Is a positive sloping curve?
A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y also decreases. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
How do you define positive and negative slopes?
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.
