1. Plot the points in the coordinate axes as in the attached picture.
2. The trapezoid is isosceles. This can be easily checked by calculating WZ and XY by the Pythagorean theorem. Or simply by the picture.
The midpoint of W and X is at (1, 2)
The midpoint of Z and Y is at (1, -1)
the line of symmetry is the line passing through these 2 midpoints. This line is the vertical line through x=1.
Answer: axis of symmetry: line with equation x=1
justification: the pairs W,X and Z,Y are symmetrical with respect to this line
Answer:
y = x+3
Step-by-step explanation:
3y-3x = 9
3y-3x+3x = 9+3x
3y = 3x+9
3y/3 = 3x/3+9/3
y = x+3
