Question

What is the slope of the line 3x + 5y = 15?

Answer 1

`"slope "=-3/5`

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+5y=15" into this form"`

`"subtract "3x" from both sides"`

`5y=-3x+15`

`"divide all terms by 5"`

`rArry=-3/5x+3larrcolor(blue)"in slope-intercept form"`

`"with slope "=-3/5" and y-intercept "=3`
