Answer:
The answer is y= 5/4x+1
Step-by-step explanation:
y=mx+b
-4=5/4(-4)+b
-4=-5+b
+5 +5
1=b
So the equation of the line that passes through the point (-4,-4) and has a slope of 5/4 is y=5/4x+1 .
Answer:
8π/5
Step-by-step explanation:
Length of an arc, L
L = θ / 360° * (2πr)
r = Radius = 4 ; θ = 72
Hence,
L = 72/360 * (2π4)
L = 1/5 * 8π
L = 8π/5
