For each order pair ,determine whether is it a solution to 7x+4y=-23

Simplifying

7x + -4y = 23

Solving

7x + -4y = 23

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

7x + -4y + 4y = 23 + 4y

Combine like terms: -4y + 4y = 0

7x + 0 = 23 + 4y

7x = 23 + 4y

Divide each side by '7'.

x = 3.285714286 + 0.5714285714y

Simplifying

x = 3.285714286 + 0.5714285714y

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
