Question

Determine which system below will produce infinitely many solutions. (2 points)

-6x + 3y = 18
4x - 3y = 6
2x + 4y = 24
6x + 12y = 36
3x - y = 14
-9x + 3y = -42
5x + 2y = 13
-x + 4y = -6

Answer 1

the one that is 2 versions of the same line

Answer 2

a scalar multiple of the other

Answer 3

if you multiply the first equation by some constant.. and you get the second equation, they are the same line, overlapping at infinitly many points

Answer 4

try (-3) times the first equation, in C

Answer 5

or re-arrange them to a different form, like y = mx+b and see that they are the same lines, slope and y-intercepts

Answer 6

i think its c? @DanJS

Answer 7

yeah,
if you try to solve the system , you get a true statement, like 7=7 or something,

Answer 8

so its c @DanJS

Answer 9

can you help me with another one @DanJS
