How do you determine a line of a best fit or a slope of a graph?

The line of best fit is found by statistical calculations which this site is too crude for. Look up least squares regression equation if you really wish to follow up. The slope of a graph is the slope of the tangent to the graph curve at the point in question. If the function of the graph is y = f(x) then this is the limit, as dx tends to 0, of [f(x + dx) - f(x)]/dx.

How do you determine the slope of a straight line on a graph?
Slope of a straight line on a Cartesian coordinated graph is 'rise over run' = y2-y1/x2-x1 = change in 'y'/change in 'x'
How do you determine a slope from a graph?
Slope = (vertical change)/(horizontal change), commonly referred to as rise/run. If the graph is a straight line, then you can count squares or measure how much change in vertical, over a specified change in horizontal. If it is a curve, then you need to have a tangent line (a line that touches the curve at a specific point and has the same slope as the line), then you can determine the slope of that line using the method described, above.
How do you determine velocity using a position-time graph?
You can't determine velocity from that graph, because the graph tells you nothing about the direction of the motion. But you can determine the speed. The speed at any moment is the slope of a line that's tangent to the graph at that moment.
The slant of a line on a graph is called?
the slope.
The slope of a line on a distance time graph represents?
The slope of a line on a distance-time graph represents the speed or velocity. The steeper the line is and the greater the slope of the line is, the faster the object is moving.

What is the slope of the line tangent to the curve on a position-time graph at a specific time?
The slope of the tangent line in a position vs. time graph is the velocity of an object. Velocity is the rate of change of position, and on a graph, slope is the rate of change of the function. We can use the slope to determine the velocity at any point on the graph. This works best with calculus. Take the derivative of the position function with respect to time. You can then plug in any value for x, and get the velocity of the object.
Is the steepness of a line on a motion graph is called a slope?
"Slope" is the steepness of the line on any graph.
How do you determine velocity using a position-time graph?
You can't determine velocity from that graph, because the graph tells you nothing about the direction of the motion. But you can determine the speed. The speed at any moment is the slope of a line that's tangent to the graph at that moment.
What is the slope of a graph line?
it is impossible to tell the slope of a line graph without proper points to evaluate from.
How do you tell whether a graph shows a constant or variable rate of change?
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.
The graph of which line has a slope of 2?
The graph of the equationy = 2x + any numberis a straight line with a slope of 2.
The slant of a line on a graph is called?
the slope.
What is the slope of a line on distance time graph?
acceleration
Is the first derivative of a function is a constant then its graph is?
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
A smooth line that reflects the general pattern in a graph?
The line that reflects the general pattern of a graph is called a trend line.
