The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4
An equation is an expression that shows the relationship between two or more number and variables.
Given the function:
y = 2.78x - 4.4
When x = 4:
y = 2.78(4) - 4.4 = 6.72
The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4
