Investigation 9 The graphs of the trajectory lines _, L, L. L.. L. and L. of six agricultural planes are given in the diagram 1 Examine the lines , D.. 1.. D. L. and . . List any common characteristics shared by two or more lines. Lines L. [green). L, [black] and L, [blue] have the following equations: Ly=x+1 L,:y=-2x-3 2 Find the equations of the lines /, (purple], L, (orange] and I, (lime]. Give the equations in the form y = wix+ k, where me is the gradient and & is the y-intercept. Use the equations of lines D. L.. L. L. L. and I, to complete the table below. Line Gradient V-intercept Examine the gradients and the j -intercepts of the lines 4 Conceptual If two lines are parallel, what is the relationship between their gradients? What about perpet dicular lines and their gradients? What can you tell about the j-intercepts of parallel or perpen 5 Conceptual |Can you tell from the equations of two ines whether they are par
