Solve the following system of equations:
-5x-3y=7
-3x-4y=2

point form (-2,1)

equation form

x=-2 ,y=1

Step-by-step explanation:

Solve by elimination where you try to cancel out one variable. Let us go for x.

-5x-3y=7 becomes -15x-9y=21

-3x-4y=2 becomes -15x-20y=10

   -15x-9y=21

-(-15x-20y=10)

11y=11

y=1

Now we can find x.

-3x-4y=2

-3x-4(1)=2

-3x=6

x=-2

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
