Which ordered pair is a solution of the system of equations? y equals 3x plus 1
y equals 5x -3

(2,7)

Step-by-step explanation:

y=5x_3 (1 ) , y=3x+1 ( 2)

then, 5x_3=3x+1

5x_3x=1+3

2x=4

x=2

substituting in 1 or 2

then y=7

then the order pair (2,7)

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.
