Graph the equation 14. a . c . b . d . Are the graphs of the lines in the pair parallel? Explain . 15. a. b. c. d. No, the slopes are different Yes, since the slopes are the same and the y-intercepts are different. No, since the y-intercepts are different. Yes, since the slopes are the same and the y-intercepts are the same. 16) Which graph represents the following system of equations. Y = 2x – 2 Y = -x + 5 A) B) C) D) 17) Solve for x and y using substitution. y = 4x – 8 y = 2x + 10 18) Graph the system. Tell whether the system has no solution, one solution, or infinitely many solutions. y = 2x + 1 y = 2x – 4 19) Solve the system using elimination. 7x + 15y = 32 x – 3y = 20 20) Suppose you invest $10,410 in equipment to make a new board game.
