Answer:
The lines moves lower.
Step-by-step explanation:
The steepness of a line is related to the slope, m.
b is the y-intercept, not the slope.
b is where the line intersects the y-axis.
Changing b changes the vertical position of the line.

Choice B) Commutative Property is the answer
The commutative property of addition says that we can add two numbers in any order. For example: 2+3 = 5 and 3+2 = 5.
In general, the rule can be written as x+y = y+x. The x and y are simply placeholders for numbers. You can think of them as empty boxes to write a number inside. In this case, we have 7.2 for one of the boxes and -5.5 as the other value in the other box.
Answer:
1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies
2) Now let's consider any real number a no matter positive or negative we will have that:

Or in the other case:

So then we can conclude that the expression is a general rule and is true
Step-by-step explanation:
For this case we can verify if the following expression is true or false:
The sum of x and it’s opposite is always zero?
If we want to proof this we need to show that for any number is true.
1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies
2) Now let's consider any real number a no matter positive or negative we will have that:

Supplementary angles add up to 180°
-> The measure of an angle that is supplementary to a 71° angle is 180° - 71° = 129°
