On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3). Which point could
Fynjy0 [20]

MN goes through

  • (2,3)
  • (-3,2)

Slope:-

  • m=2-3/-3-2=-1/-5=1/5

Slope of perpendicular line:-

  • y+3=-5x+15
  • y=-5x+12

Check one by one

  • 0=-5(-12)+12=60+12=72
  • 2=-5(2)+12=-10+12=2

Yes option B is correct
