Adata set consists of the following data points: (3, 5), (5, 8), (6, 13)the line of best fit has the equation y = 2.5x – 3. what does this equation predict for a value of x = 3?

For this case we have the following equation:
 y = 2.5x - 3
 For x = 3 we have:
 y = 2.5 (3) - 3.
 Rewriting:
 y = 7.5 - 3.
 y = 4.5
 Therefore, the ordered pair that predicts the line is:
 (x, y) = (3, 4.5)
 
 this equation predict for a value of x = 3:
 (x, y) = (3, 4.5)
