Question

Given y + 6 = 10 (x - 9), find the point used to write this equation.

  1. (10, 9)
  2. (6, -9)
  3. (-6, 9)
  4. (9, -6)

hintHint:

The line y - y1=m(x - x1) passes through (x1, y1)

The correct answer is: (9, -6)


    Given equation is y + 6 = 10(x - 9).
    Step1 : The line y - y1=m(x - x1) passes through (x1, y1)
    Step 2 : On comparing we get x1 = 9 and y1 = -6 .
    So , Point is (9, -6).

    point of the line  y - y1=m(x - x1)
    is (x1, y1) which is used to write the equation .
