For two lines to be parallel, their slope must be the same.
To find the slope, we can use the form:
For the top line, the change in height (y value) can be seen as a - 0 or simply a, and the change in base is just -b (because our
is just 0, from the origin.
Hence, line 1's gradient is:
Now, we can repeat this process for line 2:
Change in height is -d, change in base is c
Hence, line 2's gradient is:
For the two lines to be parallel, both gradients must be the same:

Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
