Question

How do you find the slope and intercept of `-3x=6y+18`?

Answer 1

`"slope "=-1/2," y-intercept "=-3`

Explanation:

`"the equation of a line in "color(blue)"slope-intercept form"` is.

`•color(white)(x)y=mx+b`

`"where m is the slope and b the y-intercept"`

`"rearrange "-3x=6y+18" into this form"`

`"subtract 18 from both sides"`

`-3x-18=6y`

`"divide all terms by 6"`

`-1/2x-3=y`

`rArry=-1/2x-3larrcolor(blue)"in slope-intercept form"`

`"with slope "=-1/2" and y-intercept "=-3`
