• $$\begin{gathered} \text{True or False?} \\ \text{The gradient of the line joining }(2,5)\text{ and }(4,1)\text{ is }\frac{4-2}{1-5}\text{.} \end{gathered}$$
  $$\begin{gathered} \text{False} \\ \text{Correct Answer: }m=\frac{1-5}{4-2}=\frac{-4}{2}=-2 \end{gathered}$$
• $\text{Write the general equation of a straight line using integers }a,b,c\text{.}$
  $ax+by+c=0$
• $$\begin{gathered} \text{True or False?} \\ \text{The line }2x+3y+4=0\text{ has a gradient of 2.} \end{gathered}$$
  $$\begin{gathered} \text{False} \\ \text{Correct Answer: Gradient is }-\frac{2}{3} \end{gathered}$$
• $\text{To find the coordinates where the line }3x+2y=12\text{ crosses the x-axis, what do you do?}$
  $\text{Set }y=0\text{ and solve for }x\text{.}$
