Find the distance between the points (4,3) and (2,-1). Express your answer in simplest radical form.

Kamila [148]

Answer : B

the distance between the points (4,3) and (2,-1)

We apply distance formula

$d^2= (x_2-x1)^2 + (y_2-y_1)^2$

(x1,y1) is (4,3)

(x2,y2) is (2,1)

$d^2= (2-4)^2 + (-1-3)^2$

$d^2= (-2)^2 + (-4)^2$

d^2 = 4+16 = 20

Take square root on both sides

So $d=2\sqrt{5}$

the distance between the points (4,3) and (2,-1) is 2sqrt(5)

Help! I’ll give BRAINLIEST!

iren [92.7K]

It’s letter C.

If you start at point (0,0) and go up two over one (rise over run) to the left, you’ll be at (-1,2). Go up two over one again to the left to get to (-2,4). Your equation would be: y=-2x+0 (0 because you started at 0 so your y-intercept is 0) though since it’s +0 you can leave that out and have y=-2x. It’s a negative slope because the line would be going down to the right.
