If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.

What is the equation of the line that passes through the points (2, –1) and (6, 1)?

Zolol [24]

Y=kx+b
2k+b=-1
6k+b=1
6k+b-2k-b=2
4k=2
k=1/2
b=-2
y=1/2x-2
So your answer is option A

In an arithmetic sequence, the nth term an is given by the formula An=a1+(n−1)d, where a1is the first term and d is the common

Olin [163]

Answer: 433

Step-by-step explanation:

The given sequence : 19,42,65,88,...

We can see that the terms ha common difference as :-

$42-19=23\\65-42=23\\88-65=23$

Thus, its an Arithmetic progression with common difference (d)=23

The formula to find the nth term is :-

$a_n=a_1+(n-1)d$

Now, the 19th term of the given sequence :-

$a_{19}=19+(19-1)(23)\\\\=19+(18)(23)\\\\=19+414=433$

Hence, the 19th term of 19,42,65,88,... is 433.
