Y = x + 3 is the answer

the y-intercept is 3, so the answer should have a "+ 3" in it

when you are trying to determine the gradient (the x), you can use two methods

first method:
picture/sketch the line. If the line is going upwards (from left to right), it's positive. If the line is going downwards (from left to right), it's negative. However, this method only works for this question, you should try using the second method more

second method:
use the formula: (y - y) / (x - x)
So, you use the y from one of the brackets and subtract the y from the other bracket. Then, you put it over the x ,from the same bracket as the first y, and subtract the x from the second bracket. If you are confused, look at the picture. (Sorry for the messy explanation)

angles in a triangle add up to 180

so x = 180 - ( 70 + 90 ) = 20

this is because the two other angles in the both of the identical triangles are 70 and 90

Answer:

C

Step-by-step explanation:

The easiest way to solve this would be to find the difference between the numbers. We can do -3-(-9) to find the difference of 6. We can then make sure this is true for the rest of the sequence by adding 6 to each number.

-9+6=-3

-3+6=3

3+6=9

9+6=15

Now that we've verified that this is true, we know the answer is C

(5 organisms that live in your house. Identify them and tell me how they interact within the environment and with each other.
lubasha [3.4K]

List five living things in your house (people, animals, plants) and how they interact.

Example: Me, mom, dad, plant, dog. Me and my mom talk and I help her. Same with me and my dad. They both help me. All three of us water and take care of the plant. We play with the dog, feed him, and walk him. The dog sometimes plays with the leaves on the plant.

(I hope this gives you an idea)
