The slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –x + 6. What is the point-slope form of the equation for this line?

y = -x + 6
comparing with y=mx+c, we get
m= -1
eqn. of line passing through point (-3,8) and having slope m= -1 is
y-y' = m(x-x')
y-8 = -1(x+3)
y-8 = -x-3
x+y = 5
