If you have an equation, then the number before the x is your slope, if you have points, use the equation (y2-y1)/(x2-x1)
Answer:
4v - 7w = (101 , -36)
6u -8v = (-78 , 58)
2u +v - 4w = (40 , -4)
11u + 3w = (-88 , 89).
Step-by-step explanation:
u(-5, 7) ; v(6 , -2) ; w(-11,4)
4v - 7w = (4*6+[-7]*[-11] , 4*[-2] + [-7]*4)
=(24+77 , -6 - 28)
4v - 7w = (101 , -36)
6u - 8v = (6*[-5]+[-8]*6 , 6*7+[-8]*[-2] )
= (-30-48 , 42+16)
6u -8v = (-78 , 58)
2u + v - 4w = (-10+6+44 , 14 -2 -16)
2u +v - 4w = (40 , -4)
11u + 3w = (11*[-5]+3*[-11] , 7*11 +3*4)
= (-55-33 , 77+12)
11u + 3w = (-88 , 89)

Answer:
64r -48r -144
Step-by-step explanation:
The January cost expression is ...
62p -48p -144 -432 = profit
The cost is identified as having 3 components, so the profit will have 4 components:
(selling price)×p - ((cost per unit)×p +(fixed monthly cost)) -(first month startup cost) = profit
Comparing this to the given equation, we identify the components as ...
selling price = 62
cost per unit = 48
fixed monthly cost = 144
first month startup cost = 432
We note that 432 = 3×144, so is consistent with the description of startup costs.
Increasing the selling price by $2 will raise it from 62 to 64. In February, the initial month startup cost disappears, so the profit equation becomes ...
(selling price)×r - ((cost per unit)×r +(fixed monthly cost)) = profit
64r -48r -144 = profit
