[beekaykilla]

so the asymtote is the number the line will never touch or cross in this case 0 (x)

[tiSkills]

@beekaykilla ---- Correct... the equation for the asymptote is y=0 in this case.

[kpvids2]

You can choose any x values to base the Y values off?

[tiSkills]

@kpvids2 --- Yes, but some x values work better than others. In this case, if you picked x values less than -2, your y values would quickly get higher and higher and go off the grid. If you picked x values greater than 2, the y values would be fractions with larger and larger denominators, and they would be difficult to graph.

[STEALINGSOUP]

why is the equation y=0?

[tiSkills]

@STEALINGSOUP --- the equation for horizontal lines is ' y= ' the y-intercept. In this case, we want a horizontal line that crosses the y-axis at 0, so the equation is y=0. Same thing for vertical lines, except it is ' x= '

Hope this helps!!!
