2.1 Review Worksheet, Part 1 (continued)
Find the intercepts of each line, and graph the line. 33. x + y = − 3 34. 2 x − y = 8
35. 5 x − 2 y = 10
36. − 3 x + 2 y = 6
Write each function in slope-intercept form. Then graph the function. 37. 2 x + y = 6 38. − y = − 3 x + 2 39. 3 y = − 6 + x
40. 8 x − 6 y = − 12
Determine if each line is vertical or horizontal. Then graph the line. 41. x = − 1 42. y = 0 43. x = 3.7
