Explain how to write an equivalent expression using fhe associative property. 2+ (11 + y)
2 answers:
The associative property of addition is a property which allows terms in an addition expression to be "switched around." For example, the addition property says that the following two expressions are equal:
Applying this to this problem, we can move the parentheses to cover the 2 + 11 to make a new expression, as shown below:
A new expression could be (2 + 11) + y.

Step-by-step explanation:
The line that passes through (-2, 1) and (8, 2) is:
y = (1/10)*x + 12/10
<h3>How to find the equation of the line?</h3>I assume you want to find the equation of the line that passes through (-2, 1) and (8, 2).
A general linear equation is written as:
y = a*x + b
If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:
In this case, we know that it passes through (-2, 1) and (8, 2), then:
Then the line is:
y = (1/10)*x + b
To find the value of b, we use one of the given points, for example if we use (8, 2), it means that when x = 8, we must have y = 2.
2 = (1/10)*8 + b
2 - 8/10 = b
20/10 - 8/10 = b
12/10 = b
Then the linear equation is:
y = (1/10)*x + 12/10
