Answer:
The slope is a) -5.
Step-by-step explanation:
(-6, -4)
(-5, -9)
the difference in slope is 
B, because they go by fives
Answer: B 1/3
Step-by-step explanation:
For every 3x it travels 1 y so you will get 1/3 as your answer.
At 50y the line is at 10x. By the time it is at 60 y it is at 40x. This was a change in y by 10 and change in x by 30. There fore the answer is 10/30 or 1/3.
2.
5x+6=3x+4
2x=-2
x= -1
3.
7n-29=4n+7
3n=36
n=12
The answer to this question is (2, -2) and (0, -2)
Why: imagine a graph with a line through it. When the line hits the y-axis (anywhere) the value for x is always zero. When you look at the answer, I chose, you can tell that in the second coordinate pair the first number is zero which represents x and the second number is -2 which is what you said y equals to.
Hope this helped
