Respuesta :

The slope between (3, 1) and (7, 9) is
.. (9 -1)/(7 -3) = 8/4 = 2

Answer:  The required slope is 2.

Step-by-step explanation:  We are given to find the slope between the points where x = 3 and x = 7 from the following table :

x      3       4      7

y      1        6      9

We know that

the slope of a line between the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

At x = 3, y = 1  and  at x = 7, y = 9.

Therefore, the slope between the points (3, 1) and (7, 9) is given by

[tex]m=\dfrac{9-1}{7-3}=\dfrac{8}{4}=2.[/tex]

Thus, the required slope is 2.
