Answer:
y= -5/2x + 3/2
Step-by-step explanation:
(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.
(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.
Plugging in the two points, hence y= -5/2x + 3/2

Formula for arc length = (angle/360)×2×pi×r
(70/360)×2×pi×4 = 4.89cm
