Find the equation of the straight line passing through (0, 8) and (6, 4) in the form y = mx + c.

let's solve this calculus problem step-by-step.

The given curve is $y = (x-1)^2 + 4$.
The straight line passes through the points $(0, 8)$ and $(6, 4)$.

a) Find the equation of the straight line in the form $y = mx + c$.

Step 1: Calculate the gradient ($m$) of the straight line.
The line passes through $(x_1, y_1) = (0, 8)$ and $(x_2, y_2) = (6, 4)$.
