NAME\newline \qquad DATE \qquad PERIOD \qquad Solving Linear Equations by Graphing\newlineEstimate Solutions by Graphing Sometimes graphing does not provide an exact solution, but only an estimate. In these cases, solve algebraically to tind the exact solution.\newlineExample: WALKING You and your cousin decide to walk the 77-mile trail at the state park to the ranger station. The function d=7−3.2t d=7-3.2 t represents your distance d d from the ranger station after t t hours. Find the zero of this function. Describe what this value means in this context.\newlineMake a table of values to graph the function.\newline\begin{tabular}{|c|c|c|c|}\newline\hlinet t & d=7−3.2t d=7-3.2 t & d d & (t,d) (t, d) \\\newline\hline 00 & \qquad 00 & 77 & \qquad 11 \\\newline\hline 11 & \qquad 22 & 33.88 & \qquad 33 \\\newline\hline 22 & \qquad 44 & 00.66 & \qquad 55 \\\newline\hline\newline\end{tabular}\newlineThe graph intersects the t t -axis between \qquad 77 and \qquad 88, but closer to \qquad 77. It will take you and your cousin just over two hours to reach the ranger station.\newlineYou can check your estimate by solving the equation algebraically.\newlineExercises\newline11.
