Yes
Numbers to the right of zero on a number line are positive numbers; to the left are the negative numbers.
On a number line, the positive numbers extend to the right of zero, and the negative numbers extend to the left of zero. So -3.4 is 3.4 to the left of zero.
A number's distance from zero on a number line is its magnitude or "absolute value."absolute value or magnitude.absolute value
Absolute Value.
line graphs show a change over time
No.
A bar graph's data doesn't always start with zero but the scale on the y axis should. If you are not going to start the scale with zero then you have to put a squiggly line at the bottom to show that you skipped this space.
yes a graph has to start from a point 0.
No. And for examples where they don't look at graphs where the x-axis is years. If the scales do not start at zero, this fact should be clearly indicated.
Unless it is a direct proportion, the straight line does not have to start from zero.
Bar graphs and line graphs do not. Straight line, parabolic, and hyperbolic graphs are graphs of an equation.
A horizontal line on a position-time graph or a stationary line on a velocity-time graph represents the motion of an object with zero net force. These graphs indicate constant velocity motion, where the object is moving at a consistent speed in a straight line.
circle graphs add up to 100% , bar and line graphs don't
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.
