1. Find the coordinates of point A in the coordinate plane if it is located at (3, -5).
Answer: The coordinates of point A are (3, -5).
2. Plot the point with coordinates (2, 4) on the coordinate plane.
Answer: Point (2, 4) is located at (2, 4) on the coordinate plane.
3. Find the distance between the points (1, 3) and (4, 7) on the coordinate plane.
Answer: To find the distance between two points, we can use the distance formula:
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
= sqrt((4 - 1)^2 + (7 - 3)^2)
= sqrt(3^2 + 4^2)
= sqrt(9 + 16)
= sqrt(25)
= 5
Therefore, the distance between the points (1, 3) and (4, 7) is 5 units.
