Answer:
x² - 100
Step-by-step explanation:
Use the FOIL method. The FOIL method is the way in which you multiply the terms:
FOIL stands for First, Outside, Inside, Last. Multiply:
First:
x * x = x²
Outside:
x * 10 = 10x
Inside:
-10 * x = -10x
Last:
-10 * 10 = -100
Combine like terms:
x² + 10x - 10x - 100
x² + (10x - 10x) - 100
x² - 100
x² - 100 is your answer.

Answer:
--- Slope intercept
--- Standard form
Step-by-step explanation:
Given
The attached linear graph
Required
The equation
Select any two points on the line


Next, calculate the slope (m)

So, we have:


The slope intercept is then calculated using:

So, we have:



Multiply through bu 4

Subtract 3x from both sides
--- Standard form
Yes it is the most simplified version
