19. use the variable expression 3x - 1.

a. evaluate the expression when x = -3.-2,-1.0, 1, 2, and

a

3 (3)-1 = 10 3(-1)- 4 300-

3(-2)-1 = 73001-1=1/3(2)-1 =151

b. use your results from part (a) to write a list of ordered pairs in the form

(x, 3x - 1).

c. plor the ordered pairs (x, 3x - 1) from part (b) in a coordinate plane.
