For any line, there needs to be two points.
If the line passes through points and extends in both directions forever, it's a line.
If the line just goes between the two points, its called a line segment.
If the line goes through both points but only extends in one direction, it's a ray.
A straight line on the Cartesian plane
The gradient (slope) of the tangent to the graph at the given time - provided that it exists. If the graph is a straight line at that point, it is the gradient of that line.
A straight line on a distance - time graph represents a "constant velocity".
A straight line with a positive slope on a position-time graph is the graph of an object that's moving in a straight line with constant speed.
The graph of y = x - 8 is a straight line. The slope of the line is 1, and it intersects the y-axis at the point y = -8.
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
A straight line on the Cartesian plane
pH is a logarithmic scale; because of the way calculus and maths works, graphing such a scale against a log results in a straight line.
There is no reason why any graph should start from any particular point.
The gradient (slope) of the tangent to the graph at the given time - provided that it exists. If the graph is a straight line at that point, it is the gradient of that line.
A graph that shows speed versus time is not an acceleration graph.The slope of the graph at any point is the acceleration at that time.A straight line shows that the acceleration is constant.
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
The straight horizontal line on a graph is referred to as the x-axis. The vertical line on a graph is the y-axis.
A straight line on a distance - time graph represents a "constant velocity".
a graph that does not have a straight line
A straight line with a positive slope on a position-time graph is the graph of an object that's moving in a straight line with constant speed.
it is the line in the middle of the crosses
