Anthony has a square-shaped, wooden board. To build a door, he uses the board and cuts 3 feet off of its width. The new area of the wooden board is given by the expression below, where x represents the length in feet.
x(x-3)
Which statement best describes the term (x - 3)?
Answer:
The equation of the line would be y = 8x + 26
Step-by-step explanation:
In order to find the equation, we first need to note that they will have the same slope due to the definition of parallel lines. Knowing that, we can use the slope and point to find the equation.
y - y1 = m(x - x1)
y - 8 = 8(x + 2)
y - 8 = 8x + 18
y = 8x + 26
