Step-by-step explanation:
[] I gave you the explanation of going from table to graph on the last question, so I will explain graph to table.
[] First, we will plot (0, 5) as it is the y-intercept.
-> I am using a square = 2-units scale as 5 is a larger number and we can see the table goes by 2's.
-> Then, using rise-over-run for the slope, we will move up one point and 2 points to the right. Repeat. Then we will graph the line.
[] Now, we can put (0, 5) into the table.
-> For the rest, we will look at our graph.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Answer:
Step-by-step explanation:
Te equation of line is:
y = 3x + 12
Plug x = 0 in the above equation of line, we find:
y = 3*0 + 12
y = 0 + 12
y = 12
y-intercept = (0, 12)
Plug y = 0 in the equation y = 3x + 12
0 = 3x + 12
-3x = 12
x = 12/(-3)
x = - 4
x-intercept = (-4, 0)
