Answer:

Slope-intercept form of the line:

  • y = mx + b

Point-slope form of the line:

  • y - y1 = m(x - x1)

------------------------------------

Points:

  • (2;9) (4,17)

The slope:

  • m = (17 - 9)/(4 - 2) = 4

The line:

  • y - 9 = 4(x - 2)
  • y = 4x - 8 + 9
  • y = 4x + 1

----------------------------------

Points:

  • (3; -17) (-3;13 )

The slope:

  • m = (13 - (-17)) / (-3 - 3) = 4/ -6 = -2/3

The line:

  • y - (-17) = -2/3(x - 3)
  • y = -2/3x + 2 - 17
  • y = -2/3x - 15
