Question

Find the distance between the two points rounding to the nearest tenth (if necessary).

(3, -2) \text{ and } (7, 6)
(3,−2) and (7,6)

Answer 1

ok so use the distance formula
i cant type out the square root symbol so just pretend that this dollar sign is the square root symbol so the formula is
d=$(x2-x1)^2+(y2-y1)^2
so everything is under the sqrt symbol ($ in this case)

so (3,-2) and (7,6)
i find that labeling them helps so like
(3,-2) and (7,6)
x1 y1 x2 y2

now do it:

d=$(7-3)^2+[6-(-2)]^2
d=$(4)^2+(6+2)^2
d=$16+(8)^2
d=$16+64
d=$80
so distance is sqrt of 80
do u need it in radical or decimal form?
