Answer:
(x, y) = (18, 9)
Step-by-step explanation:
Assuming the figure is a parallelogram, the diagonals bisect each other. Each half of one diagonal is equal to the other half of that diagonal.
Long diagonal:
x -3 = 15
x = 18 . . . . . add 3 to both sides of the equation
Short diagonal:
y +3 = 12
y = 9 . . . . . . subtract 3 from both sides of the equation
The variable values are ...
Answer:
x=18, y=9
Step-by-step explanation:
The lines of y+3 and 12 look equal to each other. So do x-3 and 15. Because of this, we set each equal to each other and solve.
solving for x:
x-3 = 15
+ 3 +3
x=18
solving for y:
y+3=12
- 3 -3
y=9

It means the scatter plot is a line with negative slope. The relation is perfectly described by a linear equation.
