(50 Points)

Drag each description to the correct location on the table. Each description can be used more than once.

Some systems of equations and their graphs are given in the table. For each system, place the description(s) in the box that correctly describe the type of system shown.

Please helppppp :((((

Answer 1

Answer with explanation:

1.→→→ 3x-5y=15------(1)

6 x-10 y=30----(2)

Line 2 =2 * Line 1

These two lines are coincident.

Dependent

2.→→→ -2 x+4 y=-6-------(1)

Dividing both sides by , 2 we get

-x+2y= -3-----------------(1)

x+6 y=3------------(2)

These two are distinct lines ,it means they have a common point of intersection.

Consistent, and Independent

3.→→→

x-4y = -12-----------------(1)

3x-12 y= -9--------------(2)

Equation (2)=3 * Equation (1)

These two lines are coincident.

Dependent

4.→→→

3 x+y=3------(1)

6x+2y=-4------(2)

Dividing both sides by ,2 we get

3 x+y= -2

Both lines have distinct y intercepts that is ,3 and -2,but coefficient of x and y are equal. So, they are parallel lines.

Inconsistent
