Answer:
The graphs are the same because both equations have the same slope, the y-intercept only changes the place of the line. The lines are different because one line is at a different location than the other because of the difference in y intercepts.
Step-by-step explanation:
The graph it probably the same cause of the slope
y=3
15/y=20/4
or, 15/y=5
or, 15/5= y
or, y=3
0.142
divide -1 by 7 = -0.142
opposite of that would be positive
