Answer:

y = -3x + 6

Step-by-step explanation:

First, this is your current equation: y= -3x+b. Fill in one of your coordinates into the equation (it doesn't matter which one because they're both the same). It should look like this: 3 = -3(1) + b. Multiply -3 and 1 to get -3. So, this is what it should look like: 3 = -3 + b. Add 3 to both sides to get your y-intercept of 6. Go back to your original equation and plug in 6 to b. This is your final equation: y = -3x + 6. Hope this helped!

Explain why 3/4 of 16 is the same as 3 x 16 divided by 4 Please Help

Answer:

I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.

Step-by-step explanation:

Since 3/4 is a fraction, all fractions can be converted into decimals.

3/4 is also known as 75%, which can be simplified into 0.75 in decimal terms.

Now that you know that 3/4 can be simplified to 0.75, you now need to take that 0.75, and multiply it by 16. You can use a calculator to do this, or you could work it out on a sheet of paper.

An easy way to do this, is to know that 25%, (0.25) of 16 is 4. This is because 4 times 4 is 16. Knowing this, if you are looking for 75% of 16, (0.75) you can multiply 4 by 3, knowing that it is 75% of 16.

The answer to that is 12.

3 x 16 = 48 and if you take 48 and divide it by 4, you will get 12.

You can explain this by writing; I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.
