What steps would find the slope and y-intercept of the line that pass through the points (23, 9) and (-32, 14)?

• Find the slope

  m=(y-y)/(x-x)

  then Y-intercept

  b=y-mx

• Find the slope

  m=(x-x)/(y-y)

  and y-intercept is 0

• Find the slope

  m=(x-y)/(x-y)

  and y intercept is 0

• Find the slope

  m=(y-y)/(x-x)

  the the Y-intercept

  y=mx+b
