Which equation is the BEST fit for the data in the graph?
Responses
A y = 8x – 75
B y = 75x – 8
C y = -8x + 75
D y = -75x + 8
To determine which equation fits the data best, we need to analyze the slope and y-intercept of the lines in the graph.
Based on the graph, the line appears to have a positive slope and a negative y-intercept.
Among the given options:
A) y = 8x – 75 has a positive slope but a negative y-intercept, so it is a candidate.
B) y = 75x – 8 has a very steep positive slope and a negative y-intercept, so it is less likely.
C) y = -8x + 75 has a negative slope and a positive y-intercept, so it is less likely.
D) y = -75x + 8 has a negative slope and a positive y-intercept, so it is less likely.
Therefore, the equation that best fits the data in the graph is option A) y = 8x – 75.
