You can construct a residual plot, plotting the x values against the values of the residuals; if there is a non-linear pattern in the residual plot then it would not be suitable to use linear regression, whilst if there is no noticeable pattern (ie. the points are randomly scattered) then the relationship is linear and a line of best fit could be appropriate.

Answer: the options that apply are
1) w(2w + 4)
5) 2w² + 4w
Step-by-step explanation:
The formula for determining the area of a rectangular garden ins expressed as
Area = length × width
The length of a garden is four more than twice its width, w. The expression for the length would be
Length = 2w + 4
Therefore, the expression that represents the area of the garden would be
w(2w + 4)
Expanding the brackets, it becomes
2w² + 4w
