Set up a system of equations:
2x+3y=6
x-3y=9
You can solve this with elimination by adding the two equations together:
3x+0y = 15
3x=15
x=5
Then, plug this value back into either of the original equations to find the y value:
5-3y=9
-3y=4
y= -4/3
The point of intersection is (5,-4/3)
Slope of the line;
slope=

Slope=

Slope,m =

y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
Answer:
20
Step-by-step explanation:
x - 9 = 11
+9 +9
x = 20
Transformational properties allow systematic movement of congruent figures while maintaining or adjusting their orientation.
