| Topic | Straight Lines & Coordinate Geometry |
| Type | Midpoint of line segment |
| Difficulty | Easy -1.3 This is a straightforward C1 coordinate geometry question requiring only direct application of standard formulas: midpoint formula and gradient-intercept form. Both parts are routine calculations with no problem-solving or conceptual challenge—students simply substitute values into memorized formulas. |
| Spec | 1.03a Straight lines: equation forms y=mx+c, ax+by+c=0 |
The points $A$ and $B$ have coordinates $(1, 2)$ and $(5, 8)$ respectively.
\begin{enumerate}[label=(\alph*)]
\item Find the coordinates of the mid-point of $AB$. [2]
\item Find, in the form $y = mx + c$, an equation for the straight line through $A$ and $B$. [4]
\end{enumerate}
