Plot the following points:

a. 3,7
b. -4,5

To plot the given points on a graph, follow these steps:

1. Draw a coordinate plane with an x-axis (horizontal) and a y-axis (vertical).
2. Locate the point (3, 7) on the graph. Start at the origin, which is the point (0, 0). Move 3 units to the right on the x-axis and then go up 7 units on the y-axis. Place a dot at the intersection of these coordinates.
3. Locate the point (-4, 5) on the graph. Start at the origin again. This time, move 4 units to the left on the x-axis and then go up 5 units on the y-axis. Place a dot at the intersection of these coordinates.

Once you have plotted the points, you can connect them to visualize any patterns or relationships between them.
