"Describe the characteristics of each graph (for example, . . . ., zero or non-zero intercept value)."
I guess a zero intercept value would be if the line is on the point (0,0)/the origin. But what if the line starts at (0,1) or (2,0). Because then the x intercept is zero or the y intercept is zero... Would these be considered as having the characteristic of a "zero intercept value" or a "non-zero intercept value"?
The answer is 10,000 dollars because 1,000,000 dollars got gaven to trump by his dad and it was "a small loan of $1,000,000" lol I'm joking
To describe the characteristics of each graph, including the intercept values, let's start by clarifying the terms "x-intercept" and "y-intercept."
The x-intercept of a graph is the point at which the graph intersects the x-axis. In other words, it is the value of x when y is equal to zero. Similarly, the y-intercept is the point where the graph intersects the y-axis, and it represents the value of y when x is equal to zero.
A zero intercept value refers to the situation where the graph intersects the x or y-axis at the origin, which is the point (0,0). In this case, both the x-intercept and y-intercept are zero.
Now, let's address your specific examples:
- If a line starts at (0,1), then it has a non-zero y-intercept value. This means that when x is zero, y is equal to 1. However, the x-intercept value would still be zero because the line doesn't intersect the x-axis.
- If a line starts at (2,0), then it has a non-zero x-intercept value. This means that when y is zero, x is equal to 2. However, the y-intercept value would still be zero because the line doesn't intersect the y-axis.
In both of these cases, the intercept that is not zero (either x or y) would be considered as having the characteristic of a "non-zero intercept value." This is because the intercept that is non-zero provides valuable information about the graph's behavior and equation, allowing us to infer different characteristics from those with a zero intercept value.
It's important to note that intercept values are just one characteristic of a graph, and there are other aspects to consider, such as slope, concavity, symmetry, and more. These characteristics can provide further insights into the behavior and properties of the graph.
