Solve the problem.The table represents a linear function. Find the slope and y-intercept of the line and use your answers to write an equation for f(x). 
A. f(x) = 1.5x + 4.8 B. f(x) = -1.5x + 4.8 C. f(x) = -4.8x + 1.5 D. f(x) = 4.8x - 1.5
Solve the problem.On a Touch Tone phone, each button produces a unique sound. The sound produced is the sum of two tones and is given by 
and y = sin (2?ht), where l and h are the low and high frequencies (in hertz = Hz) associated with that button. 
The tone produced is thus given by y = sin (2?lt) + sin (2?ht). Write an expression that models the tone by pressing the "9" button as a product of sines and cosines.
A. y = 2 sin (357?t) cos (2061?t) B. y = 2 sin (2329?t) cos (625?t) C. y = 2 sin (2061?t) cos (357?t) D. y = 2 sin (625?t) cos (2329?t)
