8 The line 2y = x + 4 is drawn on the grid. (a) (i) On the grid, draw the line x + y + 2 = 0. (ii) The region R is represented by these three inequalities. 2y=>x+4 x+y+2=>0 y=<2 On the grid, shade and label the region R. (b) Line L is perpendicular to the line 2y = x + 4. Line L passes through the point (1, 8). Show that the equation of line L is y = 10 - 2x. (c) Use an algebraic method to find the coordinates of the point of intersection of the lines 2y = x + 4 and y = 23 - 2x.
