Math Problem Statement
Answer this
Solution
Let's break this problem down step-by-step.
We are given two functions:
- The function in the graph appears to be , and we are tasked with identifying its slope and y-intercept.
- The second function provided in the equation form is .
Comparing the slopes:
-
For the graph function :
- By observing the graph, the line has a negative slope. To calculate the slope, we look at two points on the graph: one at (the y-intercept) and another at .
- Slope formula: .
- So, the slope of is .
-
For the function :
- The slope is clearly because the equation is in slope-intercept form, , where is the slope.
Comparing the y-intercepts:
-
For :
- From the graph, the y-intercept occurs at , meaning the y-intercept is 3.
-
For :
- The y-intercept is also 3 because the equation shows that when , .
Conclusion:
- The slopes are different: for and for .
- The y-intercepts are the same: 3 for both functions.
Therefore, the correct answer is D. The slopes are different but the y-intercepts are the same.
