Y = mx + n

m slope = Δy / Δx 

for point(-7,43) and (4,-12)

Δy = -12 - 43 = -55
Δx = 4 - (-7) = 11

m = - 55/11 =  -5

choose a point for instance point (-7,43) and insert it into the equation, you get:

43 = -5 * (-7) + n = + 35 + n

n = 43 - 35 = 8

so: 

y = -5x + 8

Slope = (-12 - 43)/(4 +7) = -55/11 = -5

y = mx + b
43 = -5(-7) + b
43=35+b
b = 8

equation
y = -5x + 8

Refer to the figure to the right.
Law Incorporation [45]

Step-by-step explanation:

Use arc length:

s = rθ

where r is the radius and θ is the angle in radians.

a) First, convert the angle to radians (1 degree = 60 minutes).

77 ⁵⁰/₆₀° × (π radian / 180°) = 1.358 radians

s = rθ

s = (9.67 in) (1.358 rad)

s = 13.1 in

b) s = rθ

4 in = (9.67 in) θ

θ = 0.414 radians

θ = 23.7°

θ = 23° 42'
