According to (-b/a)
So --9/3=3
(-b/a) is the equation of the slope
The formula for finding the slope is:
(second y - first y)/(second x - first x)
so for this question you can say:
(6 - 4) / (2 - (-1)) = (2)/ (2+1) = 2/3 so the slope is 2/3 :)))
i hope this is helpful
have a nice day

Can I have Brainliest
Answer:
None of the options are correct.
Step-by-step explanation:
Let the complex number is a + ib
Given distance from origin = 17 units
Now, by distance formula distance of a point from the origin =
1) <u>Check for 2 + 15 i</u>
here, 
≠ 17
2)<u> Check for 17 + i</u>
here, 
≠ 17
3)<u> Check for 20 - 3 i</u>
here, 
≠ 17
4) <u>Check for 4 - i</u>
here, 
≠ 17
Hence, none of the options are correct.
Answer:
(8.5, - 2 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 43 → (1)
2x - 3y = 23 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the term in x
- 6x + 9y = - 69 → (3)
Add (1) and (3) term by term to eliminate x, that is
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in either of the 2 equations and solve for x
Substituting into (1)
6x + 4(- 2) = 43
6x - 8 = 43 ( add 8 to both sides )
6x = 51 ( divide both sides by 6 )
x = 8.5
Solution is (8.5, - 2 )
