y = - 4x - 2

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - 4x - 5 is in this form

with slope m = - 4

• Parallel lines have equal slopes

y = - 4x + c ← is the partial equation

To find c substitute (- 2, 6 ) into the partial equation

6 = 8 + c ⇒ c = 6 - 8 = - 2

y = - 4x - 2 ← equation of parallel line

If you would like to know which expression represents the amount of time Joe exercises, you can calculate this using the following steps:

Keith ... x hours a week
Troy ... three hours less than Keith: x - 3
Joe ... two times more than Troy: 2 * (x - 3)

The correct result would be D) 2 * (x - 3).
