We are given two points: (4, -8) and (8, 5)
General equation of a line: y = mx + c
First find m (the gradient). There is a formula for this: (change in y)/(change in x) = gradient
(5 - -8) / (8 - 4) = (13) / (4) = 3.25 = m
y = 3.25x + c
Now we need to find c (the y-intercept; the value of y when x=0).
Substitute in any one of the coordinates - let's use (8, 5)
(5) = 3.25(8) + c
(5) = 26 + c
c = -21
The equation of the line: y = 3.25x - 21
I think that this answer is correct - sorry if it seems rushed.
Hope this answer helps :)

Step-by-step explanation:
Answer:
B) 6(x+2y) + 4 = 6x + 12 y + 4
Answer:
The answer is 10
Step-by-step explanation:
- 14 -(17 - 5) + 8
- 14 -17 + 5 + 8
- -3 + 13 = 10
- 10 is your answer.
