Answer:

Step-by-step explanation:

It is a function. Every x has only 1 y associated with it. You cannot find an exception to this rule.

Stated another more common way: if you take a ruler and lay it flat on the graph so that the ruler is parallel to the y axis, you will find the ruler will go through only one y for every x. That's called the vertical line test.

VashaNatasha [74]

Equations:

2x+105=-3x+130

subtract 2x from both sides 

105= -5x+130

Subtract 130 from both sides

-5x= -25

isolate the variable

x=5 

Plug back in

2(5)+105= -3(5)+130

115= 115
