Answer: -7.5
Step-by-step explanation: 
area = 1/2bh. 
area = 1/2(x+6)(5)
area = x/2 + 15
area = x/2 = -15
area = x = -7.5
area = -7.5

Answer:
y = 15x
Step-by-step explanation:
The biggest giveaway here is the other answers have<em> </em>+ a whole number at the end of the equation. We would see this + as a y-intercept on the graph.
Since our line had no y-intercept and starts from zero, y =15x can be used to represent the graph shown
Another way to know this is to look at the points marked on the line. There is a point at (2, 30). By plugging these co-ordinated into y = 15x we get 30 = 30, which makes sense
