Just wanted to check my answer for this question,
If the slope of line f is 2, and a line d is parallel
to the line f, what is the slope of line d?
my answer is 1/2

Yep. So absolutely anything parralel to that line must have a slope of 2:
parallel means the lines will not intersect. Slope is a measure of the rise and run of the graph. A slope of 2 means each successive point is up 2 units and right one unit from the previous point. So the only way two lines can be parallel and not meet is if they rise and run (slope) at the exact same rate. This is why the answer would be 2. Just for the sake of it, this would be 2 and 1/2 slopes:
Ok, I understand now. I thought because if the slope of line f is 2, and a line d is perpendicular then its -1/2 thats why i thought it would be just 1/2. Unless I am wrong about that as well.
Youre right about perpendicular.
So in order for them to cross in this way, they must be opposite signs. Not only are they opposite signs, theyre movements are flipped.
The picture isnt perfect, so of course it doesnt show perfectly right angles, but they basically do opposite things, which is what allows them to be perpendicular.
Okay that was helpful. I understand. But just so i am clear so if you have a parallel slope that means that they are the same
Yes, parallel lines have the exact same slope.
Oh ok thanks Psymon
I am logging off now thanks for explaining it to me. I now understand it.
