Question

Choose the correct graph of the given system of equations.

3y − x = 4
y + 2x = −1

A) One solution (-1,1)
B) One solution (1,1)
C) No solution
D) None of the above

Answer 1

X=-1, y=1
A) looks like a good choice.

Answer 2

A

Answer 3

One solution (-1,1)

Answer 4

A) (-1,1)

Answer 5

Ok thanks guys. :) And one more.. Kinda long..

Part 1: Provide a system of TWO equations in slope-intercept form, with only one solution. Using complete sentences, explain why this system has one solution.

Part 2: Provide a system of TWO equations in slope-intercept form with no solutions. Using complete sentences, explain why this system has no solutions.

Part 3: Provide a system of TWO equations in slope-intercept form with infinitely many solutions. Using complete sentences, explain why this system has infinitely many solutions.

Answer 6

You dnt have to do the complete sentances part, thats too much..

Answer 7

Which part do you want to do first?

Answer 8

1 please

Answer 9

You do know what the slope intercept form looks like and we need to provide two equations

Answer 10

mhmm, y=mx+b

Answer 11

I am having trouble posting my answers. It is taking a long time.
y=3x-16
y=-2x+14
I believe these two only have one solution.

Answer 12

The solution is x=6 and y =2. There is only one solution because these two lines only intersect at one point (6,2)

Answer 13

That should take care of Part 1:

Answer 14

You ready for Part 2:???

Answer 15

y=3x-2
y=3x+2

No solution parallel lines that never intersect. Thats Part 2.

Answer 16

You take care of Part 3. Bye and good luck.
