Question

What is the difference between points a (1,2) and b (9,17)

Answer 1

Explanation:

-distance formula:
`d = √((x_2 - x_1)^2 + (y_2-y_1)^2)`

(1,2) is (
`x_(1) , y_(1)`) respectively

(9,17) is
`x_(2) , y_(2)` respectively

-plug in the values to the formula

`\sqrt (9-1)^(2) +(17-2)^(2) \\\sqrt 8^(2) +15^2\\\sqrt 64 + 225\\\sqrt 289\\\\17`
