In what quadrant does the solution of the equation fall?

y = x - 1

y = -3x - 5

Answers
1.
2.
3.
4.

Answer 1

ebcuase both right sides are equal to x we can write
x - 1 = -3x - 5
add 3x to both sides
4x - 1 = -5

can you continue to find the value of x?

Answer 2

* are equal yo y

Answer 3

-1 = 9?

Answer 4

or -1 = 1?

Answer 5

@welshfella

Answer 6

you have to have x in the equation
x = -1

4x - 1 = -5
add 1 to both sides
4x -1 + 1 = -5 + 1
4x = -4
divide both aides by 4
4x -4
-- = --
4 4

x = -1

Answer 7

now to find the value of y plug x = -1 into y = x - 1:-

y = -1-1 = ?

Answer 8

what is -1-1 equal to?

Answer 9

-1

Answer 10

@welshfella

Answer 11

No -1-1 = -2

Answer 12

so what quadrant

Answer 13

so the solution of system of equations
is x = 1 , y = -2

that is the point (-1,-2)

Answer 14

so which quadrant is that in?

Answer 15

so the second quadrant?
