Choose the appropriate function for the number line 4.
To solve this problem, we need to determine the function that corresponds to the line labeled "4" on the number line.
The line labeled "4" is depicted in orange and appears to pass through the origin, indicating that the y-intercept is 0. Therefore, the equation has the form .
Upon examining this line, we observe that it is direct and passes through the origin at a angle to both axes, suggesting that the slope is 1. This is to say, for each unit increase in , also increases by the same magnitude.
We next compare our result to the given function choices:
The line labeled "4" directly matches Choice B, , as both the direction and slope align with our observations.
Therefore, the function corresponding to the number line labeled "4" is .
Which function describes the line numbered 1?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
- Observation shows that line '1' in red goes through the origin (intersects at the point (0,0)), confirming that the y-intercept, , is zero.
- Given that this line descends from left to right, the slope is negative. Therefore, the most likely function representation given the described visual descent is .
Thus, the function describing the line numbered '1' is .
