\n" ); document.write( "\n" ); document.write( "Since there is no

variable in your original equation, you cannot put the equation into slope-intercept form. In the first place, you can't just willy-nilly substitute

for

. There are points on the plane where

and

have the same value but they are NEVER the same thing. The only thing you can do with the given equation is add 4 to both sides, thus:\r

-coordinate is 11, and the

-coordinate is any real number value. In other words a vertical line that intersects the

-axis at the point

. As you should be aware, the slope of a vertical line is undefined, and a vertical line, except the one at

is parallel to and never intercepts the

-axis. So with an undefined slope and no

-intercept, it is impossible to represent the equation in slope-intercept form.\r
