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

-2y = 6 + 4x
y = -2x - 3

when solved,this system of equations will have infinite solutions because u r dealing with the same line

Solution:

There will be Infinitely many solutions.

Explanation:

We have been given the system of equation

2x+y=-3.............(1)\\-2y=6+4x...........(2)\\

The slope intercept form of a line is given by y=mx+b, where m is the slope and b is the y intercept.

Let us write both equations in slope- intercept form

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

The second equation is

-2y=6+4x\\\\\text{Divde both sides by -2}\\\\y=-3-2x

Now, we have to solve this system of equation.

We have calculated the values of y for both equation. Hence, both should be same

-2x-3=-2x-3\\0=0

We got a true condition.

Hence, there will be Infinitely many solutions.

Which statement correctly describes the slope of the linear function that is represented by the data in the table?
777dan777 [17]
Slope=change in y/change in x

one way is t pick 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)

pick some points
(8,4) and (8,0)
slope=(0-4)/(8-8)=-4/0=undefined
the slope is undefined
so you could say there is no solpe


answer is D

Simplify.
pantera1 [17]
-12 + 9 - (-3) - 11

Remember PEMDAS: This is the order of operation.
P-Paragrahp
E-Exponent
M-Multiply
D-Divide
A-Add
S-Subtract

1st step: PEM
-(-3) is actually -1 * -3 = + 3

-12 + 9 + 3 - 11

2nd step: D is not possible, so we do A.
9 + 3 = 12

3rd Step: Subtract
12 - 12 - 11 = 0 - 11 = -11 CHOICE B.
