Technically is can be anything you want it to be since you did not equate this expression to any value.
It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
An equation where c = 5
p+c=r.
A quadratic equation.
no

An equation where c = 5
c is the speed of light in vacuum.
An equation where c = -86
p+c=r.
A quadratic equation.
no
That is the standard equation to graph a line.
The letter 'c' in that equation represents the speed of light.
C = speed of light
c = the speed of light.
You would do it it by oppisites. 3+2+4=9 which equals C.
