Which of the following are ordered pairs for the equation y = -2x - 3?

Question

(0,-3) (-1,-4) (-1,-5)


(0,-3) (1,4) (-1,-5)


(0,-3) (1,-4) (-1,-5)


(0,-3) (1,-5) (-1,-1)

Answer 1

Just set up a table of values:

   x      y

   0    -3            y = -2(0) - 3 = -3

  1     -5            y = -2(1) - 3 = -5

 -1    -1             y = -2(-1) - 3 = -1

 

(0,-3), (1,-5), (-1,-1)
