What else can I help you with?
Is there a relationship between the sign positive or negative of the slope of a line and the angle the line makes with the x axis?
yes, the slope of the line is the tangent of the angle
Is there a relationship between the sign positive or negative of the slope of a line and the angle the line makes with the x-axis?
Yes.
What does it mean when the slope of the line varied?
It means that the relationship between the x and y variables is not linear.
What relationship is used to find the slope of a line?
slope=rise over run
What is the difference between slope of 0 and no slope?
No slope is undefined i.e. a vertical line slope of 0 is a horizontal line... i believe...
What is the relationship between slope and a perpendicular line?
If a line has a slope m then a line perpendicular to it has a slope -1/m ( negative inverse). For example if a line has slope positive 2, its perpendicular has slope -1/2
Is there a relationship between the sign positive or negative of the slope of a line and the angle the line makes with the x axis?
yes, the slope of the line is the tangent of the angle
A straight line on a graph means there is a what relationship?
A direct relationship if the slope of the line is positive. An inverse relationship if the slope of the line is negative.
How does finding slope compare to finding the rate of change between two variables in a linear relationship?
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
Is there a relationship between the sign positive or negative of the slope of a line and the angle the line makes with the x-axis?
Yes.
What does it mean when the slope of the line varied?
It means that the relationship between the x and y variables is not linear.
What is the difference between a line with a slope of zero and no slope?
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
What is the slope relationship of perpendicular lines?
They are negative reciprocals. So if the slope of a line is x, the slope of the perpendicular line is -1/x
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
The straight line on the graph tells us about the relationship between two temperatures?
A line on a graph that compares two variables, temperature for example tells us a great deal about the relationship of these variables in the experimental system. When the line is straight it reflects a direct and proportional relationship between the two factors.
What are the effect of slope?
The slope of a line represents the rate of change between two variables. A positive slope indicates a direct relationship, where one variable increases as the other increases. A negative slope indicates an inverse relationship, where one variable decreases as the other increases. The steeper the slope, the greater the rate of change between the variables.
What relationship is used to find the slope of a line?
slope=rise over run
