Question

What is the distance between the points G (-15, -7) and H (-4, -7)?

Answer 1

d=11

Explanation:

The distance between two points is calculated by the formula:

`d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)`

where (x_1;y_1) and (x_2;y_2) are the given points.

But, in this case, you can note that G and H's second coordinates are equal, then you simply can calculate

`d=|x_2-x_1|=|-4+15|=11`
