State whether the graph of each linear realation ship is a solid line or a set of unconnected points explain your reasoning
the relationship between the height of a tree and the time since the tree was planted

The graph of  each linear relationship is a solid line.

     The graph of the given  linear relationship i.e.

The relationship between the height of a tree and the time since the tree was planted is:

A solid line since the height of a tree planted is continuous as the height of a tree increases continuously increases  or may remain constant in some time interval and hence the graph is a solid line.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

i’m sorry but i don’t know sorry
