➷ Pick any two sets of values
I will just select the first two:
(-2,-9) , (1,3)
First, you need to find the slope
slope = difference in y values / difference in x values
slope = (3-(-9)) / (1-(-2))
slope = 12 / 3
slope = 4
Substitute the slope into the general equation of a line form with one of the coordinates:
3 = 4(1) + c
3 = 4 + c
c = -1
The equation would be y = 4x - 1

Answer:
A) 5,
Step-by-step explanation:
Answer: Option A, the square root of 40, is an irrational number.
Step-by-step explanation:
We are given 4 options:
- the sqrt of 40
- the sqrt of 49
- the sqrt of 100
- the sqrt of 9
All but one are perfect squares. Let's find out which one is not a perfect square.
The sqrt of 49 is 7. 7 times 7 is equal to 49.
The sqrt of 100 is 10. 10 times itself is equal to 100.
The sqrt of 9 is 3. 3 times 3 is equal to 9.
What about the square root of 40?
We know it's not a perfect square, and it's somewhere between 6 and 7. So, the hint from the question tells us that imperfect squares are irrational. Then this must be the answer!
The answer is c 16. Square cm
which means the sum of the 100 numbers must be
