7. Using the graph of y = 2, graph the following: (show each step) (a) y=-2 (b) 3-2-3 (c) y = 2-3-1 8. Find the equation of the line passing through the points (-3,-4) and (-2,-8). 9. Determine whether the lines are parallel, perpendicular, or neither. (a) y=-5x+6,y=-5x+4 (b) 3x+y=4, x-3y+1=0 (c) x-2=3, y=2 10. Find the x-intercepts and y-intercepts of the graphs equations. Also, test for symmetry about the x-axis, y-axis and the origin. (a) y=2-9 (b) x+zy + y=0 11. Find the inverse of the following functions and verify that (fo)(x)=1. (a) y = -9 (b) y (x-2)2 where
