For each pair of points, find the slope of the line that passes through both points.
Georgia [21]

Step-by-step explanation:

a. (1,1) and (7,5)

b. (1,1) and (5,7)

c. (2,5) and (-1, 2)

d. (2,5) and (-7,-4)

Slope of the line that passes through the points

  The slope = \frac{y_{2} - y_{1}  }{x_{2} - x_{1}  }

a. (1,1) and (7,5) ;

    slope  = \frac{5-1}{7-1}   = \frac{4}{6}

     slope = \frac{2}{3}

b. (1,1) and (5,7)

      slope  = \frac{7-1}{5-1}  = \frac{6}{4}

      slope = \frac{3}{2}

c. (2,5) and (-1, 2)

      slope = \frac{2-5}{-1 - 2}  = \frac{-3}{-3}

       slope  = 1

d. (2,5) and (-7,-4)

      slope  = \frac{-4 - 5}{-7 - 2}  

       slope = \frac{-9}{-9}  = 1
