x–8. Line u is parallel to line t and passes through (8,5). What is the equation of line u?
Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.

Answer 1

Slope of line t is -1/8, so line u has the same slope. Use point-slope with (8,5):

y - 5 = -1/8 (x - 8)
y - 5 = -1/8 x + 1
y = -1/8 x + 6

So the equation is y = -1/8 x + 6.
