A line is the locus of points which what?
A line is the locus of points such that the gradient (slope) between that point and one fixed point in the plane is a constant. Technically, that definition does not include a vertical line because its gradient is not defined! You could get around that this by requiring that either the gradient is a constant or, if it is undefined, then the inverse gradient (dx/dy) is constant.
What is the equation of a line which has gradient 2?
Y=2x+c where c is arbitery constant
How do you evaluate graphs of proportional relationships?
They are straight lines through the origin and their gradient is the constant of proportionality.
Which constant tells you what the value of maximum and minimum?
Not a constant, but the differential, i.e. gradient, of the equation. It = 0 at maxima and minima, where the curve is at its turning-point(s).
What does k correspond to in a direct variation function?
k is the constant of variation and is the gradient (slope) of the relevant graph.
