Question

I need help solving theses 3 problems I don't understand and need help.

Answer 1

.

From the image;

The two points are (-5, 3) and (-2,-3)

The distance between two points is given by:

`D=√((x_2-x_2)^2+(x_2-x_2)^2)`

On substitution

`\begin{gathered} D=√((-2--5)^2+(-3-3)^2) \\ \\ D=√((3)^2+(-6)^2) \\ \\ D=√(45) \\ D=6.71units \end{gathered}`

Therefore the distance between two points on the graph is 6.71units
