Answer:
y = - 2x + 2
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 ) = (4, - 6) and (x₂, y₂ ) = (0, 2 )
m = = = = - 2
The line crosses the x- axis at (0, 2 ) ⇒ c = 2
y = - 2x + 2 ← equation of line

*NOT THE ANSWER** BUT this is how its done
The dollar value v(t) of a certain car model that is t years old is given by the following exponential function. v(t) = 29,900(0.80^t) Find the initial value of the car and the value after 12 years. Round your answers to the nearest dollar as necessary
V(0)=29,900 X .80^0=29,900 X 1=$29,900 initial value of the car.
V(12)=29,900 X .80^12
V(12)=29,900 X 0.068719476736=$2,054.71value of the car after 12 years.

Answer:
90 mph
Step-by-step explanation:
Against wind DATA:
distance = 600 miles ; time = 5 hrs. ; rate = 600/5 = 120 mph
With wind DATA:
distance = 600 miles ; time = 2 hrs ; rate = 600/2 = 300 mph
Equations:
p + w = 300
p - w = 120
2p = 420
p = 210 mph (speed of the plane in still air)
Since p+w = 300, w = 300-210 = 90 mph (speed of the wind)
