7
4
x+2. Perpendicular to line t is line u, which passes through the point (2,

2). 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:

If the slope is 7/4x : y=-4/7x-6/7

Explanation:

1) Find reciprocal of slope: 7/4 becomes -4/7

2) insert into equation y=mx+b: y=-4/7x+b

3) solve for "b" by substituting x and y with the point (2,-2): -2=-4/7(2)+b

b=-6/7

4) write final equation: y=-4/7x-6/7
