Answer: OPTION B
Step-by-step explanation:
The equation of a line that passes through the origin is the following:
![y=mx](https://tex.z-dn.net/?f=y%3Dmx)
Where "m" is the slope of the line.
By definition, Proportional relationships have the following form:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Where "k" is the Constant of proportionality.
Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.
Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.
Then, this is:
![f(x)=\frac{3}{4}x](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B3%7D%7B4%7Dx)
Answer:
5
Step-by-step explanation:
f(-4)= -2(-4)-3
=8-3
=5
OK first change 3 3/4 to an improper fraction and that will give you 15/4. so you got that part right. Next, change the division sign to multiplication. then flip the 1/2 to 2/1. Then multiply 15 times 2 and that will give you 30. Then multiply 4 times 1 and that will give you 4. then you will have an answer of 30/4. Finally, since you a have a big number over a small number you divide 30 by 4 and that will give you 7 1/2. So it turns out that your little cheat sheet is wrong because when you check your answer you should go on Math-way to check it. Also, a little background about me is that I am in 8th grade and I am taking algebra 1 too.
