point-slope form of an equation :(

Ok so im homeschooled and one of the many flaws with homeschooling is that the math is much harder to understand for me (im the type of person that can get it hands on, but trying to be taught it from a book without further explanation is difficult for me to understand right away)

anyways, heres my problem(s)

Write the point slope form of an equation for the line passing through the point at (3,-6) with slope -4/3....... this is an example test and to be honest, i have no idea what they are talking about? i would look it up in my text book, but i left it at my house and forgot to grab it before catching a plane to visit my grandpa.

The others are:

Write an equation in slope intercept for for the line through points (2,4) and (6,-2)

Determine the slope and y-intercept of the graph of 12+3y=-2x

Determine the slope of a line through points (4,-8) and (3,-6)

Find the equation in slope intercept for for the line that passes through (-3,1) and (-2,-3)

What is the slope of a line that is perpendicular to the graph of y=-1/2x+4

and last but not least

is y+2xy=3 a linear equation

Now im not asking for a handout here, just more so help understanding the steps, but honestly any help would be greatly appreciated. Thanks :)
