E.g.1 Find the missing elements of ordered pairs on graphs of two linear relations.
The graph below is drawn from two linear relations: y = -x + 4 y = x - 2
i. Determine the coordinates for the intersection of the two lines.
ii. Determine the corresponding values for y for both straight lines if x = -1.
iii. Use the graph to find the values for y for the two relations.
