The question is- Determine weather the equation is a linear equation. If so write it in standard form- 7x+y+3=y

It's linear alright. x = - 3/7. A little tricky because it's a line parallel to the y axis.

This is a linear equation.
7x+y+3=y
7x+3=0 Subtract y from both sides
7x=-3 Subtract 3 from each side
x= -3/7 Divide both sides by 7
x= .04285 Reduce (this is not an exact answer whereas -3/7 is)
This is a straight vertical line.
IF that's what you actually meant to type in...if this is a homework problem I'm guessing you accidentally added that extra "y" in there on the left side...if that is correct...it's just an odd problem...or I've overlooked something simple.

The equation as you have written it is for a point, not linear, for a line. Subtracting y from each side, 7x = 3 = 0. 7x = -3. Have you miscopied?

It is a linear equation because the highest degree is 1, just rearrange the equation
7x=-3 or
x=-3/7

what is the degree of the equation? If the degree of the function is greater than 1, then it is non-linear. the degree refers to the exponent of the Y? value.
Pretty sure if the y cancels it isn't linear, because the y value is no longer finite.
Linear functions have 1 definite value for Y for each input X, and they maintain a constant ratio (slope). This does not. It's slope is "undefined."

Maybe you should start asking your teacher for help. After all, that's what teacher are for-they are there to help you.
