1. Find the general form of the equation of the line that passes through the given point and has the indicated slope.

(-2, 0), m = -2/5

* [a] 2x-5y+4=0
* [b] 5x+2y+10=0
* [c] -5x+2y-10=0
* [d] 2x+5y+4=0

2. Solve the inequality
| 2 - 6x | - 2 < 8

* [a] x > 2, x > -4/3
* [b] - 4/3 < x < 2
* [c] -4 / 3 < x < 2 / 3
* [d] x > 2/3, x < -4/3

Need some help with these!

A(-2,0) B(5,-2) <--- those are vectors
try converting the points to vectors so: v(t)= A+t(A-B)
