June 2017 Paper 1 Q1
1 On the grid below, draw a straight line through (2, 1) with gradient \(\dfrac{3}{4}\) [2 marks]

| Answer | Mark | Comments |
|---|---|---|
| Any straight line of gradient \(\dfrac{3}{4}\) or a correct point plotted, other than (2, 1) | M1 | |
| Line through (2, 1) and (\(-2\), \(-2\)) or line through (2, 1) and (6, 4) | A1 | this is the minimum length required |
Additional guidance
\(y = \dfrac{3}{4}x - \dfrac{1}{2}\) oe scores SC1
A line of gradient \(-\frac{3}{4}\), through (2, 1), tolerance as below, scores SC1
If they draw the correct line and the \(-\frac{3}{4}\) line then award 1 mark only
Tolerance of \(\frac{1}{4}\) cm square at two of the three points (2, 1), (6, 4) and (\(-2\), \(-2\))
