So:  2y = -1.  Can you solve that for y?

pphalke · Answer

do I put in 0 in place of y?

mathmale · Answer

No.  2y = -1 is an equation in y.  I'm asking you to solve this equation for y.  Isolate y.

You can do this by dividing both sides of this equation by 2.

Pls show your results.

pphalke · Answer

-1/2 is that right?

mathmale · Answer

Yes, that's right.  Write that as $$y=-\frac{ 1 }{ 2 }.$$

mathmale · Answer

Translate this equation into words.  What does it mean in terms of graphing this function?

pphalke · Answer

I don't know

mathmale · Answer

"y=-1/2" reads "y has the constant value -1/2, regardless of the x-value."

Could you visualize or actually draw a graph that suits this statement?

pphalke · Answer

no idea how I even tried desmos.com

mathmale · Answer

" y = -1/2 " translates to:  "the y-coordinate of any point of a graph is y=-1/2, regardless of x-value."

(0,-1/2) is an example; (97,-1/2) is another.  My point is that x can take on any value, but y always has the value -1/2.

Could you graph (0, -1/2)?  Start at the origin, (0,0), and move down to y=-1/2.  Place a black dot there.
