You draw a polygon on the graph
Two different things u can do
Substitution:
X-9y=12
+9y +9y
X=9y+12
-3(9y+12)+9y=36
-27y-36+9y=36
+36 +36
-18y = 72
/-18 /-18
Y = -4
Or whatever this other I’ve is called
-3x-9y=36
-1(X-9y)=(12)-1
-3x-9y=36
-x+9y=-12
-4x=24
X= -6

- A real number that cannot be expressed as a simple fraction is called an irrational number.
- It is impossible to express in terms of a ratio.
- If N is irrational, it is not equal to p/q, where p and q are integers and q is not equal to 0.
- Example: √2, √3, √5, √11, √21, π(Pi) are all irrational.
Equation is 112= 14x
x= 8
