O y = -2x + 3 ✓

  • putting the value of x as 2 & y as -1

⇢-1 = -2 x 2 +3

⇢-1 = -4+3

⇢-1 =-1 ✓

  • putting the value of x as 4 & y as -5

⇢-5 = -2 x 4 +3

⇢-5 = -8 +3

⇢-5 = -5 ✓

  • putting the value of x as 6 and y as -9

⇢ -9 = -2 x 6 +3

⇢ -9 = -12 +3

⇢ -9 = -9 ✓

O y = 2x + 3

O y = -3x + 2

O y = 3x - 2

Take 2 pairs

  • (2,-1)
  • (4,-5)

Slope:-

  • m=-5+1/4-2
  • m=-4/2
  • m=-2

Equation in point slope form

  • y+1=-2(x-2)
  • y+1=-2x+4
  • y=-2x+3
