Answer:
y = - x + 1
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (4, - 3)
m = =
= -1, hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 2), then
2 = 1 + c ⇒ c = 2 - 1 = 1
y = - x + 1 ← equation in slope- intercept form

Hello! Your answer is BELOW
Step-by-step explanation:
Car will cover 16 miles in 1 gallon of the gas.
We can solve this question by unitary method.
∵ A car used gallons of gas to drive the distance =
miles
∴ Car used 1 gallons to drive the distance =
=
=
= 16 miles
Therefore, car will cover 16 miles in 1 gallon of the gas.
Hope I helped! Hope you make an 100%.
