Answer:

Step-by-step explanation:
The standard form of a linear equation is
.
The given line has equation:

This is the point-slope form of the given line.
To find the standard form, we clear the fraction

We expand the parenthesis now to get:

We group the variables on the LHS and the constants on the RHS.


Multiply through by -1

This is of the form:
.
How much dose it cost per pound?
Answer:
1=1 times 2/2 1 + 2=2 times 3/2 1 +2+3=3 times 4/2 1+2+3+4=4 times 5/2 1+2+3+4+5=5 times 6/2
D≈2π(6371-1737.5)
d≈9267π
d≈29113.1km (to nearest tenth of a kilometer)
