Answer:
Plot the point, and draw a right triangle from that point and the x-axis.
The hypotenuse is the speed. Use A^2 + B^2 = C^2 to calculate it.
Imagine a compass on your graph. Straight up along the y-axis is North. The angle clockwise from there to the hypotenuse is the compass direction of travel. Use tan(3/4) to get the angle from the x-axis, then add 90 since it's in quadrant 4. (compass directions are never negative)
i hope that helpsss :)
good luck on everything <3
