Question

What exactly do I do...

Answer 1

7.9 units

Explanation:

You are required to find the distance between the points P and Q whose coordinates are given:

P (0, 0), Q(-4, 7)

`QP= \sqrt{ {( - 4 - 0)}^(2) + ( {7 - 0})^(2) } \\ \\ = \sqrt{( - 4) ^(2) + {(7)}^(2) } \\ \\ = √(16 + 49) \\ \\ = √(63) \\ \\ = 7.93725393 \\ \\ = 7.9 \: units`

Answer 2

Explanation:

So first you want to number your graph

The first number you want to graph is the first one on the x line, If you numbered in ones it should be 4 to the left from the center

Next graph the 2nd number on the y line, draw a line and connect the -4 and the 7
