Question

Help please I don’t understand this.

Describe how the graph of y=2x is the same and different from the graph of y=2x−7.
Explain or show your reasoning.

Answer 1

Y = 2x is the same as y = 2x - 7 because they both share the same slope.

Y = 2x is different from y = 2x - 7 because the y - intercepts are not the same.

Answer 2

Explanation:

Same: both are positive linear functions; both have positive slopes; the two graphs are parallel to one another

Different: The functions have the same slope (2). The graphs have different y-intercepts: y = 2x + 0 versus y = 2x - 7
