HELPPPP!!!! geometry plzzz..... <br> What is the distance between (3,-4) and (8,8) ?

kirza4 [7]

Answer:

Step-by-step explanation:

To find the distance, d, between two points on the Cartesian plane use the distance formula.

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

The points are (3, -4) and (8, 8), so you can use:

x1 = 3

y1 = -4

x2 = 8

y2 = 8

Now plug in all values above in the formula and evaluate it.

$d = \sqrt{(8 - 3)^2 + [8 - (-4)]^2}$

$d = \sqrt{(5)^2 + (8 + 4)^2}$

$d = \sqrt{25 + (12)^2}$

$d = \sqrt{25 + 144}$

$d = \sqrt{169}$

$d = \sqrt{13}$
