Answer:
y = 100x + 400
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 ) = (0, 400) and (x₂, y₂ ) = (1, 500) ← 2 points from the table
m = = 100
note the line crosses the y- axis at (0, 400) ⇒ c = 400
y = 100x + 400 ← equation of line
We have the sum of cubes identity
and observing that 1 + 4 = 2 + 3, we have
and
Then
Alternatively, we have the well-known sum of cubes formula
The sum under the square root is this sum with . Then
and so the square root again reduces to 15.
