Question

Through (-2,5) and (2, 1)

Answer 1

Answer:

  x + y = 3

Step-by-step explanation:

The equation of a line through two points can be found using the 2-point form for the equation of a line:

  y -y1 = (y2 -y1)/(x2 -x1)(x -x1) . . . . . line through points (x1, y1) and (x2, y2)

__

  y -5 = (1 -5)/(2 -(-2))(x +2) . . . . using points (-2, 5) and (2, 1)

  y -5 = (-4/4)(x +2)

  y -5 = -(x +2) . . . . . . equation in point-slope form

  y -5 = -x -2

  y = -x +3 . . . . . . . . . equation in slope-interept form

  x + y = 3 . . . . . . . . . equation in standard form
