Which of the points shown below are on the line given by the equation y = x - 1

  B, C, D

Step-by-step explanation:

Subtract 1 from the x-value and see if that's the value you have for y.

  A: 1 -1 = 0 . . . . not 2

  B: 2 - 1 = 1 . . . yes

  C: 4 - 1 = 3 . . . yes

  D: -3 -1 = -4 . . . yes

You can also draw a line on the graph with slope 1 and through y-intercept -1. It will pass through points D, B, and C. It will miss point A.
