Height and ForearmFred needs to write the equation of the line. He used(10, 64) and (12.5, 73) to find the slope, which is 3.6.The equation of the trend line isy = 28x + 3.6Height (in.)68y = 3.6x + 2864y = 3.6x + 10060y = 100x + 3.691310 11 12Forearm Length (in.)

Once we know the slope and one of the points on the line, we can use point slope form to find the equation in slope intercept form


\begin{gathered} y-64=3.6(x-10) \\ y-64=3.6x-36 \\ y=3.6x-36+64 \\ y=3.6x+28 \end{gathered}

The answer is y=3.6x+28
