1 answer:
Perpendicular lines have negative reciprocal slopes (in which the product of those two slopes = -1). The negative reciprocal of 1/3 is -3. Therefore, the following choices are perpendicular to y — 1 = 1/3(x + 2): You’ll have to transform option 1 into its slope-intercept form to see whether its slope is a negative reciprocal to 1/3: OPTION 1: y + 2 = -3(x - 4) Distribute -3 into the parenthesis, and subtract 2 from both sides: y + 2 - 2 = -3x + 12 - 2 y = -3x + 10 OPTION 5: You’ll also have to transform option 5 into its slope-intercept form: 3x + y = 7 Subtract 3x from both sides to isolate y: 3x - 3x + y = - 3x + 7 y = -3x + 7 OPTION 3: Option 3 also has a negative reciprocal slope of -3: y = -3x - 5/3 Therefore, the following options are the correct answers: Option 1: y + 2 = -3(x —4) Option 3: y = -3x - Five-thirds or y = -3x - 5/3 Option 5: 3x + y = 7 Please mark my answers as the Brainliest if you find my explanations helpful:
