A straight line which is not vertical.
The graph is a straight line.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
It suggests that there is very little evidence of a linear relationship between the variables.

You can decide from a graph wheter a ralationship is linear or non linear if the line is staight is linear but if the line is not straight is not linear.
The graph is a straight line.
a graph of the independent variable and dependant that shows a graph with a fixed gradient (I.E a line graph) The equation of the graph will be given by y = mx +c where m is the gradient and c is a constant
A linear relation is a straight line. A non-linear relation is not - it mayor may not be be a curve.
It's a cartesian plane.
linear graph between an independent and independent variable
Not always
It takes the shape of a line.
The slope of a speed-time linear graph represents acceleration. It indicates how quickly the speed of an object is changing over time.
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
