yes, the slope of the line is the tangent of the angle
Yes.
It means that the relationship between the x and y variables is not linear.
The slope of a line represents the rate of change between two variables on a graph. Specifically, it indicates how much the dependent variable changes for a unit change in the independent variable. A positive slope signifies a direct relationship, while a negative slope indicates an inverse relationship. The steeper the slope, the greater the rate of change.
The slope of the trend line represents the rate of change between the two variables plotted on a graph. Specifically, it indicates how much the dependent variable changes for a one-unit increase in the independent variable. A positive slope suggests a direct relationship, while a negative slope indicates an inverse relationship. The steeper the slope, the greater the rate of change between the variables.
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
yes, the slope of the line is the tangent of the angle
A direct relationship if the slope of the line is positive. An inverse relationship if the slope of the line is negative.
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
Yes.
It means that the relationship between the x and y variables is not linear.
A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.
They are negative reciprocals. So if the slope of a line is x, the slope of the perpendicular line is -1/x
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.
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.
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.
