Question

How do you find the slope & y-intercept of the equation `2x+y=5`?

Answer 1

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

`"subtract 2x from both sides"`

`cancel(2x)cancel(-2x)+y=-2x+5`

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

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