Question

Find the distance between these points
R(-1,0), S(8,6)

√(26)
√(85)
3√(13)

Answer 1

Welcome to OpenStudy! Do you know the distance formula?

Answer 2

no im totally confused

Answer 3

Distance Formula:
\(d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\)

Answer 4

ok what do i do now

Answer 5

They give us point R(-1, 0), that is going to be \(x_1, y_1\). And they give S(8, 6), that is going to be \(x_2, y_2\). So now we just substitute in the values and solve

Answer 6

85?

Answer 7

How did you get 85? What did you substitute for each value?
