Answer:
The x-intercept of L is 0
Step-by-step explanation:
1) If (a,b) and (c,d) belongs to theline L, then the equation of the line using two-points formula will be:
if we want to find the x-intercept of L we should set y=0.
getting x from that equation we will have :
using distributive propertie and common denominator will be obtain
x=
as we know that ad=bc the numerator will be equal to zero. Then x=0.
2) Using the same equation of line but using the points(m,n) and (-m, -n) we will set it as:
if we want to find the x-intercept of L we should set y=0.
getting x from that equation we will have :
them
x = 0
