I need more information to solve this question, comment below
Answer:
Y = 6 and x=6 are perpendicular because they both measure at a 90 degree angle
4) the distance between the x-values is 3 and the distance between the y-values is 4
3² + 4² = d²
9 + 16 = d²
25 = d²
√25 = d
5 = d
Answer: C
6)
d =
d = 6.1
Answer: A
