You can put this solution on YOUR website!
The line must pass through: (0,0) and (-1/8, 1/13).
.
m = slope = (0-(1/13)) / (0-(-1/8))
m = -8/13
.
y = mx +b
.
y = -8/13x + b
.
Use one of the points you have to intersect to find 'b'
.
1/13 = -8/13(-1/8) + b
1/13 = 8/104 + b
1/13 - 8/104 = b
1/13 - 1/13 = b
b = 0
.
y = -8/13x
.
8/13x + y = 0
.
8x +13y = 0
.
