you there?

Answer 4

From the graph, y value of A is 5 and y value of B is 0.
The difference in y-coordinates A - B = 5 - 0 = 5.
AC:BC = 2:3
AC/BC = 2/3 or 3AC = 2BC or AC = 2/3BC
AB = AC + BC = 2/3BC + BC = BC(2/3+1) = 5/3BC
But AB = 5
5 = 5/3BC. So BC = 3*5/5 = 3

Answer 5

The y coordinate of C is 3.
