Question

Can you help me pleaseFind the distance between the points (1,1) and (7,-7)

Answer 1

Answer:

10 units

Step-by-step explanation:

to find the distance between two points you will need to use the distance formula:

$\sqrt{(x1-x2)^{2}+(y1 - y2)^{2} }$

the x1 refers to the x coordinate in the first bracket, the x2 refers to the x coordinate in the second bracket, etc.

insert the coordinates into the equation:

$\sqrt{(1 - 7)^{2}+(1--7)^{2} }$

a double negative equals a positive

insert this equation into your calculator:

$\sqrt{(1-7)^{2}+(1+7)^{2} }$ = 10

∴ the distance between the points (1,1) and (7,-7) are 10 units

I hope this was helpful :-)
