What is the solution to the equations below ? y = 3x + 2 y = 3x - 5

• a. NO Solution because the slopes are the same and the y-intercepts are different.

• b. ONE Solution because the slopes are the same.

• c. MANY Solutions because the slopes are the same.

• d. No Solution because the y-intercepts are the same.
