Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (6, - 4)
m = =
= - 1, thus
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (6, - 4), then
- 4 = - 6 + c ⇒ c = - 4 + 6 = 2
y = - x + 2 ← equation of line
Answer:
(x, y) = (12, 6)
Step-by-step explanation:
The problem is solved much more easily by considering groups of 2 small and 1 large boxes. Such a group will have a volume of 2·10+20 = 40 ft³, so 240/40 = 6 such groups are needed.
The number of small boxes shipped is 6·2 = 12; the number of large boxes shipped is 6.
_____
To solve this graphically, we must write two equations in x and y:
x = 2y . . . . . the number of small boxes is twice the number of large boxes
10x +20y = 240 . . . . the total volume is 240 ft³
The attached graph shows the solution of these equations.
(x, y) = (12, 6)
