i decide to practice math for the first time in like 2 years and google hits me with this... was i wrong? surely google knows the difference between an expression and an equation. from what i understand, an equation has to EQUATE something. but maybe i'm just not clued into the terminological nuances of algebra enough to know when a colloquial definition of 'equation' is being used... you tell me.

You were 100% correct.
Just answer the question as it's written, not how you know it should be written.

I would argue that you are correct, since what they have written is an expression and not an equation.

All of you are fucking retarded. An equation has an equal sign. What you are looking at is a statement. Fucking normies I swear.
2x + 5 is a statement
2x + 5 = 9 is an equation.
I fail students like you on principle.

"In mathematics, a statement is a declarative sentence that is either true or false but not both."
ok guru, tell us how 2x+5 is either true or false

The funny thing is that y=2x+5 isn't even technically linear

f(x):=2x+5
f(0)=2*0+5=5
According to 4chan 5=0 I guess

If x=-2.5 it's false. Else, it's true. Seems simple enough.

All linear maps are linear functions but not all linear functions are linear maps.

In plenty of fields they're used interchangeably. It's a reasonable assumption to make

Functions and maps are the same thing, retard. You're confusing linear and affine maps. Please never post here again.

according to you f(0) should be 0?
>>16281104
linearity like all concepts in mathematics are endemic to a particular topic you can't say linear functions in algebra aren't actually linear in algebra because they're not linear in linear algebra that makes no sense... you can say (as the article does) that linearity in algebra is a special case of linearity in some other topic in mathematics, but it's going too far to say y=2x+5 is somehow not a linear function.

>according to you f(0) should be 0
According to the mathematical definition of a linear function, f(0) should equal 0*
>it's going too far to say y=2x+5 is somehow not a linear function
Why? Why should we consider affine functions to be "linear" when there's already entire fields devoted to studying actually linear functions.
Should we rename linear algebra to "origin-preserving linear algebra" to suit your whims?

Expressions have truth values. False for 0. True for literally everything else.
