Question

Find the slope of the line that passes through (-3, -4) and (7, 6)

  1. 0
  2. Undefined
  3. -1
  4. 1

Hint:

Slope of a line that passes through ( x1,y1), (x2,y2) is  m equals fraction numerator y subscript 2 minus y subscript 1 over denominator x subscript 2 minus x subscript 1 end fraction

The correct answer is: 1


    Points (-3, -4) and (7, 6).
    Step 1 : Slope of a line that passes through ( x1,y1), (x2,y2) is  m equals fraction numerator y subscript 2 minus y subscript 1 over denominator x subscript 2 minus x subscript 1 end fraction
    Step 2 : substituting the values
    = 6 -(-4) / 7 - (-3)
    equals space left parenthesis 6 plus 4 right parenthesis divided by left parenthesis 7 plus 3 right parenthesis
    =1
    1 is required slope .

    Given points ( x1,y1), (x2,y2)  the slope to pass through these points will be
    m equals fraction numerator y subscript 2 minus y subscript 1 over denominator x subscript 2 minus x subscript 1 end fraction
