Answer:
B
Explanation:
always remember that the slope is the ratio "y coordinate change / x coordinate change".
in the table we see that when x increases by 3, y increases by 3/4 (= 0.75).
this impression is confirmed by the last step, as x increases by 6, and y by 1.5 = 6/4.
so, the slope is
3/4 / 3 = 1/4
or
6/4 / 6 = 1/4
so, it is 1/4.
