Question 3
Fiesta28 [93]
Answer: y = -6x + 2

m = y_2 - y_1
/ x_2 - x_1

-10 - 8
/ 2 - (-1)

= -18/3 = -6

m (slope) = -6

y = mx + b
y = -6x +b

Find b using (-1,8)
y = -6x +b
8 = -6(-1) + b
8 = 6 + b
-6 -6
2 = b

Final answer: y = -6x + 2

To check using one of the points: (-1,8) or (2,-10)
y = -6x + 2
-10 = -6(2) + 2
-10 = -12 + 2
-10 = -10
This is a true statement.

Is it possible to draw a triangle with numbers 5,6,11
Tatiana [17]

Answer:

No

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is a^2 + b^2 = c^2\\.  

11 is the bigger side in this case, so our formula would go like this: 5^2 + 6^2 = 11^2\\.

We now calculate to see if this is true.

25 + 36 \neq 121

Therefore, the answer is wrong.
