Reduce the equation `sqrt3y+y+2=0` to (i) slope-intercept form and final the slope and y-intercept. (ii) intercepts form and find the intercepts on the axes.

Answer» We have
`(i)sqrt3x+y+2=0 Rightarrow y=-sqrt3x-2`
This is of the form `y=mx+c," where "m=-sqrt3 and c=-2`
`therefore y=-sqrt3-2` in the slope-intercept form.
Here, slope=`-sqrt3` and y-intercept=-2.
(ii) `sqrt3+y+2=0 Rightarrow sqrt3+y=-2`
`Rightarrow ((sqrt3)/(-2))x+((1)/(-2))y=1`
`Rightarrow (x)/(((-2)/(sqrt3)))+(y)/(-2)=1`
This is of the form `(x)/(a)+(y)/(b)=1,` where `a=(-2)/(sqrt3) and b=-2`
Thus, `Rightarrow (x)/(((-2)/(sqrt3)))+(y)/(-2)=1` is intercepts form.
Here, x-intercept=`(-2)/(sqrt3)` and y-intercept=-2
