Select all the expressions that are equivalent to –8.
A)80100
B)–800100
C)80 ÷ (–10)
D)–80 ÷ (–10)
E)−80−100
Answer:
The only one I can see right now is (C)
Step-by-step explanation:
Because a positive divided by a negative is negative, so 80/-10 is -8.
For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.
The expressions that are equivalent to –8 is only option C i. e 80 ÷ (–10)
What is Expression?Expression is a combination of operators, variables and numbers
Two expressions are said to be equivalent when we solve both we get the same answer.
For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers
For option C, –8 is equivalent to 80/-10 because a positive divided by a negative is negative, so 80/-10 is -8.
For option D, –8 is not equivalent to -80/-10 because a positive divided by a positive is positive, so -80/-10 is 8.
So option C is equivalent to -8.

Find the slope and y-intercept of the following graph.
Answer:
y-intercept: 3
slope: 2/3
Step-by-step explanation:
The y-intercept is the point that crosses the y-axis. In this case the y-intercept is 3.
When figuring out the slope, there are some methods. I am going to be using the rise over run method. Start at one point and go up and over untill it hits another point on a graph. Start at (-3,1). Go up 4. Go over 6. You will land on the point (3,5). Your answer will be 4/6. Simplify 4/6 and then you will get 2/3.
