8-120.

Write the equation of the line connecting the points on the function $y=\sqrt{x+1}$ at $x = 3$ and $x = 8$.

Determine the $y$-coordinates for each of the points.

Calculate the slope of the line connecting the two points.

Use a point from step 1 and the slope from step 2 to write the equation of the line.
