Question

HELP ME PLEASE ASAP

How many points of intersection are there between line A and line B if they contain the points listed?

Line A: (–4, 9) and (0, –3)
Line B: (4, –9) and (0, 3)

A. zero
B. one
C. two
D. infinite

Answer 1

Zero

Explanation:

I took the test

Answer 2

Zero

Explanation:

Lest find the slope for both lines

Using the equation for slopes

m= (y2 - y1) / (x2 - x1)

Where (x2,y2), (x1,y1) are given points from the lines

m1= (-3-9) / (0- (-4)) =-3 (slopes for line A)

m2= (3-(-9)) / (0-4) =-3 (slope for line B)

We realize that the line have the same slope, but they have not the same points, so, the lines are parallels and can not touched each other.
