Compute the average rate of change of f from x1 to x2. Round your answer to two decimal places whenappropriate. Interpret your result graphically.f(x) = 
, x1= 1 and x2= 3
A. 0.58; the slope of the line passing through (1, f(1)) and (3, f(3)) is 0.58. B. 0.71; the slope of the line passing through (1, f(1)) and (3, f(3)) is 0.71. C. -0.71; the slope of the line passing through (1, f(1)) and (3, f(3)) is -0.71. D. -0.58; the slope of the line passing through (1, f(1)) and (3, f(3)) is -0.58.
The table lists data that are exactly linear. (i) Find the slope-intercept form of the line that passes through these data points. (ii) Predict y when x = -1.5 and 4.6. 
A. y = -3.9x - 10.9; y = -5.05, y = -28.84 B. y = 3.9x + 10.9; y = 5.05, y = 28.84 C. y = 6.9x + 10.9; y = 0.55, y = 42.64 D. y = 2.9x + 10.9; y = 6.55, y = 24.24
