  1. 5
  2. 4
  3. 9
  4. 10

Hint:

Point-slope form of equation of a line is y - y1 = m (x - x1)
here m is the slope of line .

The correct answer is: 10


    Given equation is y + 6 = 10(x - 9).
    Step1 : Point-slope form of equation of a line is y - y1 = m (x - x1)
    Given equation is y + 6 = 10(x - 9).
    Step2 : Comparing we get
    Here, m = 10
    so , 10 is the slope of line .

    Given the line  y - y1 = m (x - x1)
    m will be the slope .
