Ex: Write the equation of the line whose x and y-intercepts are a and b, if
a) a=2 and b=3 b) a=4 and b=1

Ex: ABCO is a square with D(0, 2), E(4, 0).If the line DE is passing through the point B then
find the area of ABCO.

3) Equation of The Lines Which Are Parallel to x-axis:

As we studied before the slope of the line which is parallel to x-
axis is m=0.
If the line is intersecting the y axis at (0,c), then it’s equation is

y=c

Ex: Write the equation of the line parallel to x-axis and passing through the point P, if

a) P(0,4) b) P(0,-3)

4) Equation of The Lines Which Are Parallel to y-axis:
As we know the slope of the line which is parallel to y-axis is
undefined.

If the line is intersecting the x- axis at (a,0), then it’s equation is

=
