23s - 145
She would have spent $600 on the furniture, and $200 on the T.V.
Her original savings were $800.
Domain is ur x values
y = 2x...when x = -1
y = 2(-1)
y = -2.....(-1,2) satisfies this equation
y = 2x....when x = 0
y = 2(0)
y = 0....(0,0) satisfies it
y = 2x....when x = 1
y = 2(1)
y = 2....so (1,2) satisfies it
y = 2x....when x = 2
y = 2(2)
y = 4....(2,4) satisfies it
y = 2x...when x = 3
y = 2(3)
y = 6.....(3,6) satisfies it
y = 2x...when x = 4
y = 2(4)
y = 8.....(4,8) satisfies it
Answer:
The coordinates of point B are (-3,-3).
Step-by-step explanation:
Let 
, 
and 
, then we have the following formula by vectorial definition of a line segment:
![B(x,y) -A(x,y) = \frac{3}{4}\cdot [C(x,y)-A(x,y)]](https://tex.z-dn.net/?f=B%28x%2Cy%29%20-A%28x%2Cy%29%20%3D%20%5Cfrac%7B3%7D%7B4%7D%5Ccdot%20%5BC%28x%2Cy%29-A%28x%2Cy%29%5D)
