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.
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.
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 is the relationship between the slope and the pythagorean theorem?
There is no relationship between slope and the theorem, however the theorem does deal with the relationship between angles and sides of a triangle.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
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
Is there a relationship between the sign of the slope of a line and the angle the line makes with the x-axis?
Yes, there a relationship between the sign (positive or negative) of the slope of a line and the angle the line makes with the x-axisWhen a line slopes up from left to right, it has a positive slope. This means that a positive change in y is associated with a positive change in x. The steeper the slope the greater the rate of change in y in relation to the change in x.When a line slopes down from left to right, it has a negative slope. This means that a negative change in y is associated with a positive change in x.
What is a line wxtending from the upper lift to the lower right has this type of slope?
The line has a negative slope (or negative gradient).When the angle between the line and the positive direction of Ox is obtuse then the slope is negative. Conversely, when the angle is acute, the slope is positive.
Demand curve slopes downwards from left to right. this is the negative slope that shows the inverse relationship between price and demand. explain why does the demand curve slope downwards?
because demand decreases as price increases :)
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.
