1) Are Linear equations are equations that form a line

2)Which of the following equations has a slope of ½ and a y-intercept of -2?
y = -2x + ½

y = ½x + 2

y = ½x - 2

½x - 2y = 4

3)Write the equation of a line which contains the points (2,2) and (-3,12)

4)Which equation has a slope of 2 and contains the point (4,-4)?

5) The line y = 3x + 5 crosses the y axis at ______?

I don't understand where the middle number comes from, the number times x to the first power. It looks like you're doing addition when you factor the problem, but it seems like it should be only multiplication.

Example: 2x squared + 3x + 6 = 0. Where does that 3x come from or go to, because when you factor it out, you wind up with an answer like (x + something)(x + something)? The two x's times each other makes x squared. The middle number (3x in example)...?

Thanks for the help. I'm trying to learn this (again), but I'm stuck on understanding this point.
