Explain why it is a good idea to draw a graph when trying to interpret data?

Step-by-step explanation:

Graphs are really helpful because it can help you know what the ordered pairs are, what the slope is, what the asymptote is, it can tell whether the equation is linear or non linear, if it's exponential or a decay graph, & so on & so on. Graphs are really useful when doing any kind of subject... Whether it's math or even science, it's easy to use! Graphs can show you a solution, a hint, a clue!!! Once again, graphs are really helpful & useful! :D

Hope this helps you!!! :)

Not only can be more easily understood by some people, but it can also illustrate the exact course a line will take rather than just giving some of the coordinates. Furthermore, a graph is less accurate due to the fact that lines are infinite and can express all the numbers they cross rather than just giving a limited amount of numbers.

The answer for the question one is 12,( g=12), and the answer for the second question is 9,(y=9).
