plug in the x values and determine you y values .... simple calculator stuff

amistre64 · Answer

simple enough by hand as well; but its the process that is important

anonymous · Answer

To find the y-intercept   for each x coordinate. plug in the value of x in the equation and then solve for y

(9, )
When x = 9   y = (5/9)9 -3  -->  y = 5 - 3  --->  y = 2

Solve the others in a similar way

Sketch the following sets of points and determine if they are open or closed, or neither. 
(a) |z| < 1                          (b) |z| <= 1                                   (c) 0 <= Im z < 1
