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.
Is the slope of a line the coefficient of the x-term in the line's equation?
True.
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.
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 characterizes constant velocity motion on a position time graph?
A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
What is true about the graph of the line y -3x 4?
The line has a slope of -4
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.
What must be true about the slope of a line whose graph extends into quadrants II and IV?
it is a negative slope.
A constant speed has a slope of zero on a graph because no acceleration is taking place?
A constant speed means there is no change in velocity over time, so the slope of the graph is zero. This indicates that the object is moving at a steady rate without speeding up or slowing down.
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 )
Velocity is the slope of the displacement vs time graph?
Velocity is NOT the slope of the acceleration vs. time graph. Velocity is the area under the acceleration vs. time graph. Velocity is the slope of a position vs. time graph, though. For you Calculus Junkies, v = the integral of acceleration with respect to time.
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 a straight diagonal line on a distance versus time graph indicates constant speed?
The answer is TRUE because it is a straight line as the graph shows below. http://www.batesville.k12.in.us/physics/apphynet/Measurement/Images/d_vs_t2_graph.gif
