Question

how the graph of y=2x is the same and different from the graph of y=2x-7

Answer 1

The graphs have the same slope  (2) and are parallel

The difference is the y intercept

y = 2x has as y intercept of 0

where y = 2x-7 has a y intercept of -7

Answer 2

In the graph y=2x-7 is different from the graph y=2x because -7 shows where you are suppose to start in the graph (the starting point), they are parallel from each other they are the same because they are both a straight line
