Answer:
[m] slope = <u>-2</u>
[b] y-intercept = <u>-1</u> ; (0, -1)
[y = mx + b] slope-intercept = -2x – 1
Step-by-step explanation:
Given the algebraic equation 6x + 3y = -3 currently in standard form:
Ax + By = C →
By = C – Ax →
By = -Ax + C →
y = -Ax / B + C / B →
y = (-A / B)x + (C / B) →
y = mx + b →
m = -A / B. b = C / B.
6x + 3y = -3
↓ ↓ ↓
A = 6. B = 3. C = -3.
[Substitute]
m = -A / B. b = C / B
m = -(6) / (3). b = (-3) / (3)
↓ ↓
m = -2. b = -1.
↓. ↓
Slope = -2. y-intercept = -1.
_______________________
Slope is ∆y/∆x [change in y over the change in x] = y2 – y1 / x2 – x1.
The y-intercept is the point where x is 0.
The easiest way to determine this is to substitute 0 in for x in an equation and solve for y.
This means that the y intercept in coordinate form is (0, b).
Well just work out your exspression until you find one equal to -8
Three machines fill 40 boxes in an hour. One machine can fill 40/3 boxes in an hour. Following the second part of the problem, one machine would take 150/40/3 = 11.25 hours to fill 150 boxes. Machines and time are inversely proportional. Then, it would take 11.25 * 1/5=2.25 hours for 5 machines to fill 150 boxes.
