Sure, I'll do my best to assist you with your question. Please describe the question or the picture in it to me so I can provide accurate help.
The question in is "Write and equation to represent the relationship between the variables", and the picture is a graph, the main points are: (-10, 0), (-8, 300), (-6,600), (-2, 1200), (0, 1500), (2, 1800), and (4, 2100)
clearly, the slope is 300/2 = 150
and since f(0) = 1500,
y = 150x + 1500
and since f(0) = 1500,
y = 150x + 1500
Omg I'm such an idiot for not noticing that, thanks, oobleck!
