</span>
x2+6x+y2 + 9 =7 <span>+ 9</span>

(x+3)**2 + (y+0)**2 = 16

I'm really confused on point-slope form, and slope-intercept form. Can anyone help?

kompoz [17]

Point slope form is

Y-y1=m(x-x1)

-in this^ u only should put number in the y1, m, and x1
-m is your slope

Slope intercept form is

Y=mx+b

-start out with putting numbers in m and b and then you'll find your way to your y and x
