Question

A: Interpret the origin on the graph. Also, describe the scale of each axis by telling what does each unit on the x-axis and the y-axis represent.
B: Compare the slope and y-intercept for the graphs of each function in terms of the quantities.

I will give brainliest :)

Answer 1

Answer:

A: The origin is the bottom-left corner of the graph, representing 0 months, 0 books. The x-axis represents months, with a scale of 1 month per line. The y-axis represents the amount of comic books, with a scale of 4 books per line.

B: The slope of Sara is 2, since she collects 2 books per month ($\frac{20-12}{4}=2$), whereas Ashton collects 3 books per month, resulting in a slope of 3.

The y-intercept of Sara is 12, since that is the amount of comic books she started with. Ashton started with 2 comic books, so his y-intercept is 2.
