Answer 2

use 2 of the points to find the slope, then
use any of the 4 points as your (x,y) value

Answer 3

i take that back, they gave you y= 100 so the x value is 4

Answer 4

so the anwer is 4

Answer 5

slope m = (100-25)/(4-2) = 75/2
point(x,y) = (4,100)

(y-100) = (75/2)(x-4)

Answer 6

(y-100) = (75/2)(x-4) thats the anwer??

Answer 7

sorry,

Answer 8

m = (100-125)/(4-2) = -25/2

Answer 9

thanks
