For which pair of points can you use this number line to find the distance? A number line going from negative 2 to positive 8. Points are at 1 and 7.
(–4, 1) and (7, –4)
(–4, 1) and (–4, 7)
(–1, –4) and (–4, 7)
(–4, –1) and (–4, –7)

no links pleas i can not see them

just go here

its what i use

step-by-step explanation:

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
