Is it true about a line graph that the slope is constant?
No - a line graph may peak and trough depending on the data marked on the graph - a bit 'like join the dots'.
Is it true that a straight diagonal line on a distance versus time graph indicates a constant speed?
Yes. The slope, or rate, is constant. The rate being represented is speed. If the slope is a negative constant, the object is losing distance (going towards) from the orgin at at a constant speed.
Does a horizontal line has a slope of zero?
Yes, it is true; slope zero is no slope.
What point on y equals x2 is the tangent line parallel to y equals x?
That's true at the point (0.5, 0.25) where the slope of the graph is ' 1 ' .
Is it true or false that the slope of the line on a speed-time graph tells the speed?
False. If speed is on the y-axis and time is on the x-axis, then any point (a,b) on the line will tell you the speed a at any given time b. The slope of the line will tell you the change in speed with respect to time, which we call acceleration.
What must be true about the slope of a line whose graph extends into quadrants II and IV?
it is a negative slope.
Considering the graph of a line with a negative slope what is true?
the line goes down from left to right as the absolute value of the negative slope get bigger, the graph of the line gets steeper as the absolute value of the negative slope gets smaller, the graph of the line gets less steep ( apex )
What is true about the graph of the line y -3x 4?
The line has a slope of -4
A negative slope on the velocity vs. time graph indicates a negative acceleration?
True
Is it true about a line graph that the slope is constant?
No - a line graph may peak and trough depending on the data marked on the graph - a bit 'like join the dots'.
Is it true a straight line on a motion graph indicates constant speed?
Yes, a straight line on a motion graph indicates constant speed. The slope of the line represents the speed of the object, with a steeper slope indicating a faster speed and a gentler slope indicating a slower speed.
A negative slope on the velocity vs time graph indicates that the object is not accelerating true or false?
False. A negative slope on the velocity vs time graph indicates that the object is decelerating or slowing down, but it is still accelerating in the opposite direction.
True or false a negative slope on the velocity vs. time graph indicates that the object is not accelerating?
False. A negative slope on a velocity vs. time graph indicates that the object is decelerating, not that it is not accelerating. Acceleration and deceleration are both forms of acceleration, but in opposite directions.
What does the slope of a velocity vs time graph show you?
The slope of a velocity vs time graph represents the acceleration of the object. 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.
Is it true that a straight diagonal line on a distance versus time graph indicates a constant speed?
Yes. The slope, or rate, is constant. The rate being represented is speed. If the slope is a negative constant, the object is losing distance (going towards) from the orgin at at a constant speed.
Is the displacement time graph of a body moving with uniform velocity always a straight line?
A displacement vs. time graph of a body moving with uniform (constant) velocity will always be a line of which the slope will be the value of velocity. This is true because velocity is the derivative (or slope at any time t) of the displacement graph, and if the slope is always constant, then the displacement will change at a constant rate.
What does a negative slope on an acceleration vs time graph mean?
No. A negative slope means that the object is slowing down. If the object were not moving, then its velocity would be zero. The graph would be a straight horizontal line that just lays there on the time axis.
