Answer:
y = 2x + 4
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 ) = (- 2, 0) and (x₂, y₂ ) = ( 0, 4) ← 2 points on the line
m = =
=
= 2
the line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = 2x + 4 ← equation of line
The formula for area of a sector is...
A = θ
NOTE θ is converted from degree to radian
θ = 167 ×
θ =
so...
A =
A = (1/2)(316.84)(2.9146)
A = 158.42 * 2.9146
A = 461.7
