Answer:
Step-by-step explanation:
When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line, 
.
To obtain the slope from the line AB, we need two points, so the general equation will be:
The typical equation of a line is written as y = mx + b
The second line will pass through point (2, -1), so we can substitute:
y2 = mX2 + b
-1 = 
(2) + b
then the interception is 
Now to obtain a general equation for the second parallel line will be:
y = 
X + b
y = X -
(2)-1
Finally we get:
y = (x-2)-1
Answer:
The total money she saved in a year = X + 12Y.
Step-by-step explanation:
Mary got a piggy bank as a gift.
Sum of money in the piggy bank while she got it as a gift = X cents
Sum of money she saved = Y cents per month
1 year = 12 months
So, sum of money she saved in 1 year = Y × 12
= 12Y
Hence, the total money she saved in a year = X + 12Y.
