1) Graph each of these lines:
a) y = x - 5 b) y = 2x + 1 c) y = 2 - 3x d) y= (3/4)x - 1/4 e) x=3 f) y = -4 2) A line with a gradient of -2 cuts the x-axis at (7,0). Where does it cut the y-axis? 3) Find the size of the angle, to the nearest whole degree, that the line 7x-3y+5=0 makes with the positive x-axis. 4) Show that the line joining (5,1) and (-3,4) is parallel to the line 3x + 8y =1. 5) Show that the line x + 3y -25 = 0 passes through the point of intersection of the lines 2x -y +6 = 0 and 3x +y - 11 =0.
