When do you connect the dots on a graph?
You only connects dots an a graph when the variable is in constant movement never stopping.
What are the characteristics of proportional relationships?
Direct proportions may be represented by a straight line through the origin, with the equation y = kx. The gradient of the line is the constant of proportionality and is a measure of the change in the "dependent" variable for a unit change in the "independent" variable. In the case of an inverse proportionality, the graph is a hyperbola with the equation y = k/x. The constant of proportionality, k, is a measure of the change in the reciprocal of the "dependent" variable for a unit change in the "independent" variable.
In a graph what is the variable on the horizontal axis?
Independent Variable c:
What variable is placed on the horizontal axis in a graph?
The indipendant variable
Derivative of zero?
The derivate of zero - as well as the derivative of ANY constant (non-variable) number, is zero. (A graph of y = 0 for example will be a horizontal line - the slope is zero.)
How do you know if a function has a constant or variable rate of change?
If the graph is a non-vertical straight line, then the rate of change is constant. If the line is curved, then the rate of change (slope) varies.
A function wahose graph is parabola?
Any equation where variable a = some multiple of variable b2 + constant will graph a parabola.
What graph graph indicates that there is a linear relationship between the dependent variable and the independent variable?
a graph of the independent variable and dependant that shows a graph with a fixed gradient (I.E a line graph) The equation of the graph will be given by y = mx +c where m is the gradient and c is a constant

What is the slope of the graph of the equation x equals 3?
x=3 means that the x variable always stays constant, so the y variable can change as much as it wants, but x will always be 3. on a graph, this would like a vertical line. (It should be perpendicular to the x variable's line...if that helps a visual:P)
What does the slope mean on a line graph?
Rate of change of the "vertical" variable in relation to the "horizontal" variable.
On a line graph the ratio of the change in the y variable to the corresponding change in the x variable is called a lines what?
The rise and the run.
What is the line called on a line graph that is the ratio of the change in the y-variable to the corresponding change in the x-variable?
The rise and the run.
Does the independent variable on a graph cause the change in an experimental system?
No. It will only do that if the other variable is dependent on it.
A straight line on a graph means there is what kind of relationship between the dependent variable and the independent variable.?
A straight line on a graph indicates a linear relationship between the dependent variable and the independent variable. This means that as one variable changes, the other changes at a constant rate, resulting in a line with a steady slope.
