Answer:
Parallel = lines with the same slope
Perpendicular = lines whose slopes are negative reciprocals (i.e. product is –1)
Step-by-step explanation:
The first part: circle b, c, d, f (1 ³/₄ is another way of saying ⁷/₄), and h (a horizontal line <em>y</em> = <em>b</em> has a slope of 0)
The second part: circle a, d (1 ⁴/₇ is another way of writing ¹¹/₇, the negative reciprocal of –⁷/₁₁), and e
Hope this helps! Have a great day!
