Which ordered pair is a solution of the equation? − 4 x + 7 = 2 y − 3 −4x+7=2y−3

The equation is

−4x+7=2y−3

Which can be rewritten as

2y−3  = -4x +7

2y = -4x + 10

y = -2x + 5

The equation represents the line shown in the image below.

Any point that belongs to the line is an ordered pair that represents a solution

To find any ordered pair that satisfies the equation, we place an arbitrary value for x and find the corresponding y value with the equation.

For example

x = 0 ,

y = -2(0) + 5  = 5

(0,5) is an ordered pair

x = 1 ,

y = -2(1) + 5  = 3

(1,3) is an ordered pair

x = 2 ,

y = -2(2) + 5  = 1

(2,1) is an ordered pair

And so on

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
