Answer 1

Using a graphing calculator, the graph will look thus:

From the graph above, the relationship is linear and we see that the gradient is -1/2 and has a y-intercept of -3.5

Looking through the options given, the correct answer would be:

$\begin{gathered} y+4=\frac{-1}{2}(x-1) \\ \text{The correct answer therefore is option C.} \end{gathered}$
