Question

The linear equation y=3x−5y=3x−5 y equals 3 x , minus 5 is in what form.

Answer 1

I must make some assumptions here about what you may have meant by your "linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."

You've written "y=3x-5" three times on the same line of type.  Why is that?  

Let's change what you've typed to the following:

linear equation y=3x−5

separate linear equation y     equals 3x  minus 5, or y=3x-5 

Please go back and ensure that you have copied down this problem precisely as it was originally presented.  Be careful not to duplicate info (as you did in typing "y=3x-5," followed by  "y equals 3 x , minus 5."

y = 3x - 5 is, as you say, "a linear equation."  The slope of this line is 3 and the y-intercept is (0, -5).

As to form:  This is a "slope-intercept equation of a straight line."

Other forms include "General form of the equation of a straight line," "Point-slope form."
