You can use the formula for calculating the distance between two points with the coordinates given F(-2, -4) and G(1, 0)
d = SQRT ((x2 - x1)2 + (y2 - y1)2)
Give it a try
d = √((x2−x1)2+(y2−y1)2)

You can look up the Formula on the internet for a better picture of it. You just need to label your coordinates and plug them.
