Answer 2

use 2 points...(0,0) and (-6,-1)
now we will find the slope by using the slope formula
slope(m) = (y2 - y1) / (x2 - x1)
(0,0)....x1 = 0 and y1 = 0
(-6,-1)...x2 = -6 and y2 = -1
now we sub
slope(m) = (-1-0) / (-6 - 0)
slope(m) = -1/-6
slope(m) = 1/6

now use y = mx + b form
slope(m) = 1/6
use either of your points....(-6,-1)
now we sub and find the y intercept, which is b
-1 = 1/6(-6) + b
-1 = -1 + b
0 = b

so your equation is : y = 1/6x + 0...or you can just write y = 1/6x
