Answer:
Step-by-step explanation:
-7y = -10x - 8
y = 10/7x + 8/7
14= 4 pi/6 pi = 2/3
15 = 8 pi/10 pi = 4/5
16 = no

Answer:
17. 5
18. 17
Step-by-step explanation:
The distance formula is used for the purpose.
d = √((x2 -x1)² +(y2 -y1)²)
__
17. d = √((3-6)² +(1-5)²) = √((-3)² +(-4)²) = √(9+16) = √25 = 5
The distance between the points is 5 units.
__
18. d = √((-1-7)² +(12-(-3))²) = √(64 +225) = √289 = 17
The distance between the points is 17 units.
