I find it easiest to start with the 2-point form of the equation of a line.
y = (y₂-y₁)/(x₂-x₁)*(x-x₁) +y₁
where the given points are (x₁, y₁) and (x₂, y₂).
Substituting the given numbers, you have
y = (8 -4)/(3 -(-1))*(x -(-1)) +4
y = 4/4(x +1) +4
y = x +5
The desired slope-intercept form of the equation for the line is ...
y = x + 5
y = (y₂-y₁)/(x₂-x₁)*(x-x₁) +y₁
where the given points are (x₁, y₁) and (x₂, y₂).

Answer:
option A
9×10^4/2×10^2
Step-by-step explanation:
Given in the question,
length of dollar bill = 6
width of dollar bill = 3
area of dollar bill = L x W
= 6 x 3
= 18inches²
length of driveway = 30
width of driveway = 20
area of driveway = L x W
= 30 x 20
= 600 ft²
1 ft² = 144 inches²
600 ft² = 86400 inches²
Number of dollar bills that would cover Kenisha driveway = 86400 / 18
Which can also be written as
86400 = 9 x 10
18 = 2 x 10²
