The slope  of the line that passes through the pair of points (1, 7) and (10, 1) is    

The slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

The slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is  

Step-by-step explanation:

Formula of slope of line (m) :

Part 1 : Points are (1, 7) and (10, 1)

So, using formula

Slope (m)

Thus the slope  of the line that passes through the pair of points (1, 7) and (10, 1) is    

Part 2:Points (-5.5, 6.1) and (-2.5, 3.1)

So, using formula

Slope (m)

Thus the slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

Part 3 : Points (-7/3, -3) and (-5, 5/2)

So, using formula

Slope (m)

Thus the slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is
