(I must reckon, that X is a variable, and y is y-intercept)

Q: Try to use the substitution method to solve the the linear system y=3x an y=3x-7. What do you notice?
A) What happens when you graph it?
B) Explain why there is no solution.

And...


Q: Try to use the substitution method to solve the the linear system 3y-6x=15 an y=2x+5. What do you notice?
A) What happens when you graph it?
B) Explain why there is more than one solution?
