First thing: Parallel to the given line. That means the slope of your line should be the same as the the slope of x + 5y = 4. We need to find the slope of x + 5y = 4.
x + 5y = 4
5y = -x + 4
y = (-1/5)x + 4/5
The slope is -1/5
.
Second thing: Make the new line. We know a point (8,9) and the slope (-1/5), so we can use point-slope form:
y - y1 = m(x - x1)
y - 9 = (-1/5)(x - 8)
That is the equation of our line, but let's clean it up a bit:
y - 9 = (-1/5)x + 8/5
y = (-1/5)x + 8/5 + 9
y = (-1/5)x + 8/5 + 45/5
y = (-1/5)x + 53/5
y + (1/5)x = 53/5
5y + x = 53
Answer: x + 5y = 53
.
Note: Unless the problem specifically asks for a certain form (give the answer in whatever form), we want to give the answer in the form used in the problem.
