The ordered pairs below represent a linear function: (3/4 , 6 1/4) , (1 1/4 , 7 3/4) , (x , y)

which values could be the values of x and y ?

Step-by-step explanation:

(3/4 , 6 1/4)  and  (1 1/4 , 7 3/4) are two points on the line.

The change in y, going from the first point to the second, is 7  3/4 less 6  1/4, or 1  1/2.  The corresponding change in x is 1  1/4 less 3/4, or 1/2.

Thus, the slope of this line is m = rise / run = (1  1/2) / 1/2, or 3.

If we chose x = 2, y would be 3(2), or 6:  (2, 6)

If we chose x = 0, y would be 3(0), or 0:  (0, 0)

These last two results represent two possible points on the line.
