The equation that is the best model for a line of fit for the data is y = -1/3x + 7
Which equation is the best model for a line of fit for the data?
From the question, we have the following parameters that can be used in our computation:
The ordered pairs
When represented on a graph, we that the attached graph best represents it
A linear function is reprsented as
y = mx + c
Reading from the graph, we have
c = 7
So, we have
y = mx + 7
Using the points on the graph, we have
6 = 3m + 7
This gives
m = -1/3
So, we have
y = -1/3x + 7
Hence, the equation is y = -1/3x + 7
Question
A set of points is shown on the graph. Scatter plot with a point at (-3, 9), (0, 5), (1, 8), (6, 7), (8, 3).
Which of the following equations is the best model for a line of fit for the data?
y = 2/3x + 7
y = -2/3x + 7
y = 1/3x + 7
y = -1/3x + 7
