suuurrre vast resvon!!!!!!!!
Answer:
Yes.
Step-by-step explanation:
Rational numbers can be represented as fractions with integers. The denominator must not equal 0.
is already in this form. This means that it's a rational number.
Hope this helps.
y = -2x + 3....slope = -2, y int = 3
2x + 4y = 8
4y = -2x + 8
y = -1/2x + 2....slope is -1/2, y int is 2
this is graph C
1 liter is equal to 1000 milliliters, so we can multiply 200 liters by 1000 to get 200000 milliliters, which should be your answer. In general, the "milli-" prefix denotes a factor of one thousand times smaller, so 1 meter is equal to 1000 millimeters, 1 second is equal to 1000 milliseconds, and so on.
First we take the two points (-7,5) and (-5,9).
Compute the slope:
![\frac{9-5}{-5+7}=2](https://tex.z-dn.net/?f=%20%5Cfrac%7B9-5%7D%7B-5%2B7%7D%3D2%20)
Then the linear relation may be in the following form
![y=2x+b](https://tex.z-dn.net/?f=y%3D2x%2Bb)
Since the point (-7,5) is on the line, then
![5=-7(2)+b\text{ then }b=19.](https://tex.z-dn.net/?f=5%3D-7%282%29%2Bb%5Ctext%7B%20then%20%7Db%3D19.)
The relation is then
![y=2x+19](https://tex.z-dn.net/?f=y%3D2x%2B19)
.
We check that the other point are on the above line:
![2(-3)+19=13 \text{ OK}\\2(-1)+19=17 \text{ OK}](https://tex.z-dn.net/?f=2%28-3%29%2B19%3D13%20%5Ctext%7B%20OK%7D%5C%5C2%28-1%29%2B19%3D17%20%20%5Ctext%7B%20OK%7D)
W
e have then a linear relation.
