Question 78892: Find the equation of the line parallel to 4x-3y=8 and also goes through (0,5)

You can put this solution on YOUR website!
The key thing to know here is parallel lines have the same slope.
Start out by putting the given line into y=mx+b form so that you can determine what that slope is:
4x-3y=8
-3y=-4x%2B8
y=%284x%2F3%29-8%2F3
So know you know the slope (m) is 4/3.
The problem also provides you with the y-intercept of the line you are trying to find. You know the line passes through (0,5). The Y intercept of a line is by definition the point where X=0, so the Y-intercept in this case is 5.
With this information, you can now write the equation of the line, since you know the slope (m) and the Y intercept (b):
y=%284x%2F3%29%2B5
Graph these two lines out to prove to yourself that they are indeed parallel.
Good Luck,
