#ch- equation of a straight line .

Answer 1

Line is making positive equal intercepts on axes say at distance d. It means the line is passing through (d,0) & (0,d) points. therefore, the slope m = -1.
m=(y2-y1)/(x2-x1)
=(d-0)/(0-d)
=-1

equation of line passing through (x1,y1)
(y-y1) = m(x-x1)
(y-2)=-1(x-3)
y-2=-x+3
x+y-5=0
