Cameron is trying to find the equation of a line that passes through the points (-1,48) and (5,102). Does the
equation y = 9x + 57 work? Justify your answer.

Find the linear approximation of the function g(x) = 5 1 + x at a = 0. g(x) ≈ 1+ 1 5x use it to approximate the numbers 5 0.95 and 5 1.1 . (round your answers to three decimal places.) 5 0.95 ≈ 5 1.1 ≈ illustrate by graphing g and the tangent line.
