The steepness is usually referred to as the slope,usually being a fraction, like 5/2. The numerator represents the rise, and the denominator represents the run. Typically, this is remembered by rise over run. One must count, for this example, up 5 units and to the right 2 units to find the next point on the line.

The gradient. If you consider the formula for any graph, Y=mx+c, then m is the gradient of the line.
You can find the gradient by deltaY/deltaX (change in y axis divided by change in X axis).
A straight line on a velocity-time graph represents constant acceleration. The slope of the line indicates the rate of acceleration, with a steeper slope indicating a higher acceleration.
if you are reffering to a scatter graph, the straight line is called the line of best fit.
A slanting line down from left to right represents an acceleration on the velocity time graph.
The acceleration of the ball can be estimated by calculating the slope of the velocity versus time graph. If the graph is a straight line, the slope represents the acceleration. The steeper the slope, the greater the acceleration. If the graph is curved, the instantaneous acceleration can be estimated by finding the slope of the tangent line at a specific point on the curve.
It represent the distance covered is 40 metre.
A position-time graph with a straight line indicates constant acceleration. The slope of the line represents the acceleration, which is constant if the slope remains the same throughout the graph. A steeper slope indicates a greater acceleration, while a shallower slope indicates a smaller acceleration.
Any curved line will indicate a change in acceleration. Straight lines with slope indicate a steady velocity and straight lines with zero slope indicate a lack of motion.If the X axis (left to right) is for time and the Y axis (up and down) is for speed, it would curve up.
