Question

Which value, when placed in the box, would result in a system of equations with infinitely many solutions?

y = -2x + 4

6x + 3y =

-12
-4
4
12

Answer 1

do you know what a system of equations that has infinitely many solutions would look like?

Answer 2

not really i dont remember

Answer 3

A system of equations with infinity many solutions would be just like 2 lines overlapping each other. Because every point on one line is a point on another line.

Answer 4

and we have to first of all make the second equation into y=mx+b form

Answer 5

okay

Answer 6

but what number from the choices could result in the second equation having the same line as the first equation?

Answer 7

Guys, the best thing to use rn is substitution

Answer 8

You don't need to convert to y=mx+b, you have the equation in terms of y

Answer 9

i guess so

Answer 10

substitute so that
y = -2x + 4

6x + 3y =
6x+3(-2x+4) =
6x-6x+12 = ?

Answer 11

And your answer is...

Answer 12

12x?

Answer 13

What?
12 = What?

Answer 14

12 = 12 obviously.
