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 :)
Answer:
40%
Step-by-step explanation:
18+12+20=50
20/50×100=
40%
Answer: Yes
Step-by-step explanation:
For the first sugar and servings part, 4 for sugar, 2 for servings.
The ratio for this example above it for sugars to servings it 2:1. So every 2 sugars is every 1 serving and this applies to every other of the sugars and servings in the table.
Answer:
C
Step-by-step explanation:
ok so, assuming that b cannot equal 0, we can divide it on both sides
(3a - 5)/c = b/b
anything divided by itself is 1
(3a - 5)/c = 1
multiply c:
3a - 5 = c
3a = c + 5
a = (c + 5)/3
