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.

What is the positive direction on the y axis?
Oh, dude, the positive direction on the y-axis is like the upward direction. You know, where things go when they're feeling optimistic and want to reach for the stars. So, if you're looking at a graph and you see things going up, that's the positive y-direction. Easy peasy, right?
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.
Can a position time graph tell in which directionthe displacement of an object is?
Yes, a position-time graph can tell you the direction of the displacement of an object. If the slope of the graph is positive, the object is moving in the positive direction. If the slope is negative, the object is moving in the negative direction.
What does a positive acceleration position-time graph indicate about the motion of an object?
A positive acceleration position-time graph indicates that the object is speeding up or moving in the positive direction.
If a object is speeding up in the positive direction what does the displacement vs time graph look like?
The displacement vs. time graph would show a curve that is increasing in a positive direction, meaning that the object is moving forward. The slope of the graph would be positive, indicating that the object is speeding up.
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.
How is acceleration represented on a graph?
Acceleration is represented on a graph by the slope of the velocity-time graph. A positive slope indicates acceleration in the positive direction, while a negative slope indicates acceleration in the negative direction. A horizontal line on the graph represents constant velocity, with zero acceleration.
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.
What does area under velocity time graph show?
The area under a velocity-time graph represents the displacement of an object. If the area is positive, the object is moving in the positive direction; if negative, the object is moving in the negative direction. The steeper the slope of the graph, the greater the velocity.
For an object that is speeding up in the positive direction what does the displacement vs. time graph look like?
The displacement vs. time graph for an object that is speeding up in the positive direction will have a positive slope that is increasing over time. This indicates that the object is covering more distance in a shorter time interval as it accelerates.
How can you find the direction of motion from a distance x axis and time y axis graph?
To find the direction of motion from a distance x axis and time y axis graph, look at the slope of the graph. A positive slope indicates motion in the positive direction, while a negative slope indicates motion in the negative direction. A horizontal line indicates stationary motion.
What does a position-time graph indicate about an object's motion when it shows positive acceleration?
A position-time graph showing positive acceleration indicates that the object is moving in the positive direction and its speed is increasing over time.
What is slope of velocity v time graph?
The slope of a velocity vs. time graph represents acceleration. A positive slope indicates acceleration in the positive direction, a negative slope indicates acceleration in the negative direction, and a horizontal line indicates constant velocity.
