Question
Let \( f(x) = 6.1x^2 - 3.4x \). Use the difference quotient and \( h = 0.001 \) to estimate the slope of the tangent line at \( x = 5 \).

What is the slope (round your answer to **one decimal place**)? \( m = \) [ ]

What is the \( y \)-value at \( x = 5 \)? \( f(5) = \) [ ]

Use the above (rounded) slope and \( y \)-value to write the equation of the tangent line to the graph of \( f(x) \) at \( x = 5 \). Write your answer in \( mx + b \) format.

\( y = \) [ ]
