amplitude = 5
Step-by-step explanation:
The amplitude is the average of the maximum value subtract the minimum value
maximum value = 6 and minimum value = - 4, hence
amplitude = = = 5
I. xy + 2y=3 Not linear equation because is grade 2 equation (xy).
II. x-2y = y Are linear equations in two unknowns (x and y).
III. 3x + 2y = 5 Are linear equations in two unknowns (x and y).
