How would I find the slope intercept form of x+y+3=0?

denis-greek [22]

Slope-intercept form follows the formula: y=mx+ b

To find the slope intercept form of those, you need to isolate y
For example, x + y + 3 = 0. Subtract 3 and x to get y=-x-3 and that is your slope intercept form! Simple as that :)
