Question

The coordinates below represent two linear equations. How many solutions does this system of equations have?

Line 1
x y
–4 8
4 6
Line 2
x y
–1 1
3 5


A.
0

B.
exactly 1

C.
exactly 2

D.
infinitely many

Answer 1

I got exactly 1 by finding the equation of each line then setting the y values equal to solve for x .

Answer 2

Thank you! Could you help with this one? I'm pretty sure it's 0, but I'd like a second opinion.

Answer 3

you can use the same approach
do the same
find the slope use a point get the equation of the line for each line
set the y values = and solve
