Maricella plots two ordered pairs on the grid below.

 (0,-10)

Step-by-step explanation:

The equation of a line (a,b) and (c,d) is given by :-

From the given graph , the line is passing through (6,2) and (8,6) is given by :_

To find the y intercept put x =0 , we get

Hence, the y-intercept of the graph : (0,-10)
