On the same diagram, sketch the graphs of: y = |5x -2| and y = |2x| and hence solve the equation |5x - 2| = |2x|
y = |2x| is a "V" shaped graph with a gradients of 2 and -2 that inflects at the origin (0,0)y = |5x - 2| is a "V" shaped graph with gradients of 5 and -5 that inflects at the point (2/5,0) and a y-intercept of 2They intersect at x values of 2/3 and 2/7.
