## julie001 Group Title How many units apart are the points (4, -3) and (-4, 3)? one year ago one year ago

Use: $\large Distance = \sqrt{(x_2 - x_1)^2+ (y_2 - y_1)^2}$ $\large x_2 = -4, x_1 = 4, y_2 = 3, y_1 = -3$ Plug in the values and find the distance..

0?

3. waterineyes Group Title

You are not taking care of negative signs.. $Distance = \sqrt{(-4-4)^2 + (3 - (-3))^2}$

4. waterineyes Group Title

-4 -4 = -8 and: 3 - (-3) = 3 + 3 = 6

5. julie001 Group Title

7. waterineyes Group Title

I think I have put square above the brackets in the formula. You have to square them first and then add them..
