Question

The coordinates below represent two linear equations.

How many solutions does this system of equations have?

Line 1
x y
–3 5
0 4
Line 2
x y
0 4
6 2


A.
0

B.
exactly 1

C.
exactly 2

D.
infinitely many

Answer 1

what do you think?

Answer 2

hint: find the slope of each line

Answer 3

yea could u graph it or do u know a website? @nikato

Answer 4

try this?

and go to plot points and type in your points

Answer 5

you could have actually solve for it.

if you try to find the slope of each of them, you will find they both have a slope of -1/3.
and because both their y-intercept is at 4, they are the same line

Answer 6

so B @nikato

Answer 7

no. infinitely many because they are the SAME line. all there points will be the same

Answer 8

0 is for parallel lines.
1 is for two intersecting lines.
2 is impossible. two lines cant intersect at two points. they wont even be lines
