Answer:
y = 6x - 13
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 ) = (2, - 1) and (x₂, y₂ ) = (1, - 7)
m = 
= 
= 6, thus
y = 6x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, - 7), then
- 7 = 6 + c ⇒ c = - 7 - 6 = - 13
y = 6x - 13 ← equation of line
100÷3 = 3.33333 which means 3
Answer:
This means that Nathan's average speed was 12 miles per hour.
Step-by-step explanation:
54 divided by 4.5 is 12
Assuming that the interest rate in each case is the same, the only factors that come into play are the length of time, and the accessibility of the money. The longer the money is left alone, the more money it will accrue, meaning the first option "saving for retirement in 20 years" is the best option. The two below it are a shorter length of time and will therefore accrue less, and the final option is less profitable because withdrawing from the account would decrease the total interest earned.
