Answer:

Step-by-step explanation:
The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression 
In the problem given coordinate points are
(0, a) and (a, 0).
Thus, distance between these points are given by

Thus , expression
gives the distance between point (0, a) and point (a, 0) on a coordinate grid.
2(x4) = 35 - (7-4x)
+4x
2(x8)= 28
/2 /2
8x = 14
