Practise using equal gradients for parallel lines, then combining that gradient with a point or axis crossing to form an equation.
P has coordinates (-1,3) and Q has coordinates (6,4).
Find the equation of the line parallel to PQ that crosses the x-axis at x=2.
y=71x−72 or 7y=x-2 oe final answer
M1 for gradient = their (iii)
M1dep for substituting (2,0) in a linear equation with their gradient
