The equation of a line is y = mx + b. If the slope of the line (m) stays the same, the line will be parallel to the original line. What changing b does is change the y-intercept of the line, because when you make x = 0, y = b. So by making b larger, you are moving the line up the y axis.
What else can I help you with?
A graph is best used to display data that shows a change over time?
A line graph.
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.
How do you determine the rate of change in a graph?
Rate of change is essentially the same as the slope of a graph, that is change in y divided by change in x. If the graph is a straight-line, the slope can be easily calculated with the formula:Vertical change ÷ horizontal change = (y2 - y1) / (x2 - x1)
What happens to the graph of a line when the slope is negative?
Looking from left to right, or as the x values get larger, the y values are decreasing. On a graph the line would be tilted down if you follow from left to right.
Why is it okay for a graph to cross one of its's horizontal asymptotes?
There is nothing in the definition of "asymptote" that forbids a graph to cross its asymptote. The only requirement for a line to be an asymptote is that if one of the coordinates gets larger and larger, the graph gets closer and closer to the asymptote. The "closer and closer" part is defined via limits.
How does the graph nof the line changes as you make b larger but keep m the same?
The line shift upwards, parallel to itself.
What is a line graph?
A continuous graph that shows change over time.
What is a line graph that shows change over time called?
line graph
What is a graph that uses line segments to show how data change?
line graph
Does a line graph show the change at one point in time?
A line graph shows change over time.
What is the graph that measures a change over time?
Line graph
What does line graph show?
Line graphs show the relationship between the change in one variable to the change in another. (change) On a computer, a line graph shows lots of pixels.
How do you tell whether a graph shows a constant or variable rate of change?
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
This type of graph is excellent for showing business cycles?
line graphThe most preferred type of graph to use for change over time is the line graph.
The type of graph used to show continuous change?
A line graph.
What is the type of graph that is useful for showing trends or continuous change?
A line graph is useful for showing trends or continuous change. Other kinds of graph also will show these, but a line graph is usually clearest.
What does the slope of a line tell you on a graph?
the rate of change on the line.
