Answer:
y = - 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (- 4, 15)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 9), then
- 9 = - 16 + c ⇒ c = - 9 + 16 = 7
y = - 2x + 7 ← equation of line
Answer:
Find the area of the circle then divide by two
Step-by-step explanation:
8 + 13 + 14 + 7 = 42
Chinese = 8/42
Simplified = 4/21
