Question

How do you find the slope and intercept of `2x+5y=15`?

Answer 1

`"slope "=-2/5," 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 "2x+5y=15" into this form"`

`"subtract "2x" from both sides and divide terms by 5"`

`5y=-2x+15`

`y=-2/5x+3larrcolor(blue)"in slope-intercept form"`

`"with slope "=-2/5" and y-intercept "=3`
