The way to use the distance formula to classify quadrilateral include:
- Use the distance formula to measure the lengths of the sides.
- Use the slope to check whether the sides are perpendicular and form right angles.
- Use the slope to check whether the diagonals are perpendicular to each
<h3>How to illustrate the information?</h3>
The steps to calculate the perimeter and area of a polygon:
Step 1: Plot the given points on the graph.
Step 2: Connect the points and identify the figure.
Step 3: Determine lengths by counting the grid lines.
Step 4: Use a formula to calculate the perimeter and area if one exists.
Step 5: If there are no formulas for a figure, the perimeter can be calculated by summing the lengths of the sides. We might estimate the area without an area formula by counting the number of small squares enclosed.

Answer:
Step-by-step explanation:
Given
Required
x and y
Add both equations to eliminate y
Divide both sides by 6
Substitute in the first equation
Divide by -3
Answer: x = 12, y = -8
Step-by-step explanation:
If you do substitution:
4(-y+4) + 6y = 0
-4y + 16 + 6y = 0
2y + 16 = 0
2y = -16
y = -8
x = -(-8) + 4
x = 8 + 4
x = 12
