Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$

A subtending arc on a circle with a radius of 4.5 centimeters has an arc length of 8π. The measure of the angle subtended by the

ella [17]

For the answer to the question above,

the angle of 360 ° → π.d 

the angle of x ° → 8π 

You make the cross-multiply and you can get: 

x * π.d = 8π * 360 

x * d = 8 * 360 

x = 8 * 360/d → where d = 2r 

x = 8 * 360/2r 

x = 4 * 360/r → where r = 4.5 cm 

x = 4 * 360/4.5 

x = 320 °
