Question analysis
This question is looking for an equation of a straight line that is perpendicular to the one given. When finding an equation of a straight line, we need two pieces of information: the gradient, and a coordinate to find the \(\)\(y\)-intercept. As for the gradient, don't forget about the formula that relates to perpendicular lines and their gradients: \(m_1 \times m_2 = -1\). Use the given coordinate to work out the \(y\)-intercept.
