Question

How many units apart are the points (4, -3) and (-4, 3)?

Answer 1

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

Answer 2

@hang254 Can you try ?

Answer 3

i thought it was x2-x1/y2-y1

Answer 4

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

Answer 5

oh wait thats slope
