The point (1, - 3) is on the line given by which equation below?

The answer to your question is: letter B

Step-by-step explanation:

Point (1, -3)

A.   y = x - 3

Substitute the point in the lines given

    -3 = 1 - 3

    -3 = -2                      this answer is incorrect because -3 ≠ -2      

B. y = -3x

   - 3 = -3(1)

   - 3 = -3                     this answer is correct because -3 = -3

C. y = 3x

   -3 = 3(1)

   -3 = 3                       this answer is incorrect because -3 ≠ 3

D. y = -x + 3

   -3 = -1 + 3

   -3 = 2                       this answer is correct because -3 ≠ 2

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
