## hang254 How many units apart are the points (4, -3) and (-4, 3)? one year ago one year ago

1. ash2326

Use the distance formula, distance between two points with coordinates A( x1, y1) and B (x2, y2) is $D=\sqrt{(x2-x1)^2+(y2-y1)^2}$ Just plugin the value of two points

2. ash2326

@hang254 Can you try ?

3. hang254

i thought it was x2-x1/y2-y1

4. ash2326

That's the reverse of slope, it's of no use

5. hang254

oh wait thats slope

6. hang254

sorry, ill plug it into the distance form.

7. ash2326

8. hang254
