Answer:
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
