Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

In which form is the following function written? y = - 2(x – 3)(x + 5)
