What is the angle between a line of a graph and a positive direction of the x-axis?

The angle is the arc-tan of the gradient of the line. That is to say, the tangent of that angle is the gradient of the line or the angle between the straight line and the positive x-axis.
Arc tan may also be written as tan-1 but that is frequently confused with 1/tan or the cotangent function.

Which graph shows a positive correlation between x and y?
Any graph where, from left to right, the slope goes upward (assuming the axes are labelled in the standard way).
How do you draw a 145 degree angle?
Assume its a reference angle, meaning it goes from the x axis and than around in the counter clockwise direction. The top half of the graph is 180 degrees, and the first quadrant is 90. Since the angle is between these two numbers,we know its in the second quadrant. 145-90 = 55 degrees. 90-55 = 35. 35 degrees above the negative x axis.
How is a bar graph and a pictograph alike?
Bar graph and pictograp are ploted on a horizontal line and in a positive quadrate
What does a graph look like when both sets of values increase?
The graph will have a positive slope and that means the line will graph from the lower left and will be higher on the Right.
Where is the positive and negative belong to the quadrants graph?
Same , equal
When an odd function has a negative leading coefficient what happens to the graph?
the left end of the graph is going in a positive direction and the right end is going in a negative direction.
What happens as the absolute value of the slope gets smaller the graph of a line gets?
Line turns towards x - axis and angle between positive x direction and line gets reduced
Which side of a graph is positive?
You can draw a graph any way you want to, as long as you label both axes clearly, to show which direction is positive and which direction is negative, on each axis. Typically ... the way people are accustomed to looking at a graph ... numbers on the x-axis are positive on the right half, and numbers on the y-axis are positive on the top half.
For an object that is speeding up in the positive direction what does the displacement vs. time graph look like?
a graph curving upward
What is the difference between a speed time and a velocity time graph?
speed does not indicate direction, so there is no negative on the graph.
Which statement correctly describes the graph of g(x) if g(x) f(x - 6)?
The graph of g(x) is the graph of f(x) shifted 6 units in the direction of positive x.
Difference between a directed graph and an undirected graph in a computer program?
In an undirected graph, an edge is an unordered pair of vertices. In a directed graph, an edge is an ordered pair of vertices. The ordering of the vertices implies a direction to the edge, that is that it is traversable in one direction only.
What does the slope of a linen on a distance - time graph represent?
The speed. Also, if a positive slope represents the speed in one direction, the negative slope is the speed in the opposite direction.
Why the value of cos positive for negative value of angle?
The cosine of an angle is the adjacent side of the angle of a triangle divided the hypotenuse. If you plot the adjacent side as x on an x -y graph, for negative angles less than 90 degrees the adjacent side is positive and the hypotenuse is always positive, so you get a positive. The cosine is positive int e upper right and lower right quadrants
Can a position time graph tell in which directionthe displacement of an object is?
Yes. If the slope is positive, the direction of the displacement is positive (e.g. north, east, or right). If the slope is negative, the direction of the displacement is negative (e.g. south, west, or left).
How voltage become zero in centre point?
If you have an alternating current, which changes direction, and we graph the direction in terms of positive and negative, then at some point, as the current changes from positive to negative, and from negative to positive, it must pass through zero. If you imagine a car, driving forwards, that then changes direction and drives in reverse, there must be a point when it is not moving. Changes of direction, or voltage, are not instantaneous.
For an object that is speeding up at a constant rate in the positive direction what does the velocity vs time graph look like?
A line angled upward
