Answer 2

Answer:

Let

′

a

′

be the x intercept of the line.

Hence y intercept will be −1−a.

Therefore the equation of the line in slope intercept form will be

a

x

+

−1−a

y

=1

Since it passes through (4,3)

a

4

+

−1−a

3

=1

4(−1−a)+3(a)=(−1−a)a

−4−4a+3a=−a−a

2

−4−a=−a−a

=4

a=±2

Hence the equations of the possible lines are
