Determine wether each equation is linear or not. then graph the equation y finding and plotting ordered pair solutions. show work. (hint: let x=-3, -2, -1, 0, 1, 2) 27. x+y=3 28. y-x=8 29. y=4x 30. y=6x 31. y=4x-2 32. y=6x-5 33. y=|x|+3 34. y=|x|+2 35. 2x-y=5 36. 4x-y=7 37. y=2x^2 38. y=3x^2 39. y=x^2-3 40. y=x^2+3 41. y=-2x 42. y=-3x 43. y=-2x+3 44. y=-3x+2 45. y=|x-2| 46. y=|x-1| 47. y=x^3
