Answer:
1/8
Step-by-step explanation:
x-8y=-1
First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
-8y = -x-1
y = 1/8x +1/8
The slope is 1/8 and the y intercept is 1/8
The slope for parallel lines is the same for all parallel lines
1/8
Lets say x = 89.99 and y = 56.49
P% * x = y
P% = y/x
56.49/89.99 = 0.6277
0.6277 * 100 = 62.77
But because we are looking for how much off the sale is:
100% - 62.77%
= 37.23%
The sale price is 37.23% off.
