Question
Which equation BEST represents the line of best fit for the scatter plot? (1 point) Responses y=x+3 y is equal to x plus 3 y=−3x−2 y is equal to negative 3 x minus 2 y=−3x+2 y is equal to negative 3 x plus 2 y=x−3
The line appears to have many dots going from the below negative y-axis to the upper x-axis 'positive'

Based on your description of the scatter plot, it seems like the line of best fit should have a negative slope, as it moves from the lower negative y-axis to the upper positive x-axis.
From the options you've given, the equations that represent lines with a negative slope are:
1. \( y = -3x - 2 \)
2. \( y = -3x + 2 \)
Since you mentioned that the line moves from below the negative y-axis to the upper positive x-axis, the y-intercept is likely positive (crossing the y-axis above zero). This suggests that the equation \( y = -3x + 2 \) might be a better fit.
Therefore, the best choice for the line of best fit according to your description of the scatter plot is:
**\( y = -3x + 2 \)**.
