Question

For the line y - 3 = 2(x + 4), the slope is 2 and passes through the point _______.

  1. (-4, 3)
  2. (3, -4)
  3. (-3, -4)
  4. (-4, -3)

Hint:

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

The correct answer is: (-4, 3)


    Given equation is y - 3 = 2(x + 4)
    we can rewrite as y - 3 = 2( x - (-4) )
    The line y - y1=m(x - x1) passes through (x1 , y1 ) .
    Step 1 :  x1 = -4
    step 2 :  y1 = 3
    So , the Point is (-4,3)

    the line will pass through  ( x1 , -y1 ) .
