1. maybe you mean sin [pi(x-6)/4]

sin (pi/6) = .5
(x-6)/4 = 1/6
6 x - 36 = 4
x = 40/6 = 20/3

3. y = -1 x + b
4 = -1(-2) + b
2 = b
so
y = -x + 2

4. Find an equation of the line that satisfies the given conditions
Through (-2,4); slope -1
How would you solve that by using the point slope form and writing it in the general equation of a line? ax +by + c =0
