Consider, pls, this option:
1. if a required line has a form y=ax+b, then points A(-1;6); B(6;k) and C(20;3) belong to it.
2. According to the item 1 it is possible to make up the system of equations for A and C:

Knowing, that a=-1/7 and b=41/7, it is possible to write the equation of required line:

3. Using coordinates of point B:

Answer: 5.
I think it’s 20 but I may be wrong
Answer:
(1/4 x 1 ) = 0.25
or (1/4) x 1 = 0.25
Step-by-step explanation:
We are doing the opposite to finding 25%
Which is 1/4 of 100%
We do this an opposite (not as inverse)
To find percentage increase as you can compare below.
or as percentage increase
230 x 0.25 (x 100) = 287.50
Even though we are not finding increase for 1/4 by changing it to decimal form, this practice does use the (x1) element in brackets and does identify the distribution.

Step-by-step explanation:
5(-3) + 2 = (-15) + 2 = -13.
-4(-3) + 5 = 12 + 5 = 17.
Since -13 ≠ 17, x = -3 is not a solution.
