1. ### Slope of a Straight Line

Hello, I am learning about the straight line and understand what the terms "rise" and "run" represent very well. I also understand how they are derived from the points positions in the plane. I really do not understand why the slope of a straight line is defined as "rise over run". How come is...
2. ### In complex numbers - equation of straight line

Hello everyone Please let me know what this say : "Show that the point representing (z1+z2)/2 is the midpoint of the line segment joining the points for z1 and z2" This means I should write equation of straight line of two complex number ? How can I do it and solve it , I'm little confused ...
3. ### I've been making straight Bs, but I had to drop Calculus II? How did I get so lost?

Well, here's what I've done so far in Math. I took College Algebra last fall in 2014, and then took Trigonometry over Winter Term. I took Precalculus in the Spring, and then took Calculus I over the Summer. I passed, and I was set to take Calculus II this fall, but I had to drop it a week in...
4. ### General form of an equation of a straight line

Ok this seems easy but I am little confused... I am trying to find the general equation of a straight line that does not pass through the first quadrant. Looking at y= mx +c , I realise m will have to be negative and c negative for sloping lines but I can't encapsulate the vertical lines and...

7. ### Solving cubic equations using straight line?

Hi, I'm having trouble with part c of this question. Solving algebraically I can see that the solutions are x=0, x=2, x=-2 but I can't see how find these solutions by "drawing a suitable straight line on the grid"? I must be missing something obvious here! Thanks
8. ### vector-equation of straight line
