What else can I help you with?
Is the constant of variation the same as slope?
yes y=kx is the formula for direct variation, and k represents constant of variation which can also be called slope.
What does k correspond to in a direct variation function?
k is the constant of variation and is the gradient (slope) of the relevant graph.
Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
What is the variable k in a direct variation?
the slope
Do the slope of direct variation changes as you move along the graph?
No.
Can you have two direct variation equations with same slope?
Yes.

Difference between the graphs of linear equations and a direct variation?
Linear has a slope direct does not but both go through the orgin
Can slope k of a direct variation be positive?
The slope of the graph of a direct variation is always positive.
When is a linear function considered to be a direct variation?
Direct variation means that a linear function can be written as y = kx. The y-intercept must be (0, 0). The constant, k, is the slope.
What is the variable k in a direct variation?
the slope
Find the constant of variation and the slope of the given line from the graph of y equals 2.5x?
find the constant of variation and the slope of the given line from the graph of y=2.5x
Do the slope of direct variation changes as you move along the graph?
No.
Is constant of proportionality equivalent to the slope?
Yes, the constant of proportionality is equivalent to the slope in a linear relationship. In a direct variation where one variable is proportional to another, the constant of proportionality represents the rate of change between the two variables, which is precisely what the slope indicates in a linear equation. Thus, both concepts describe how one quantity changes in relation to another.
Does a direct proportion have to have a slope of 1?
No, a direct proportion does not have to have a slope of 1. A direct proportion means that two quantities increase or decrease together at a constant ratio, which can be represented by the equation (y = kx), where (k) is a constant. The slope of the line in a graph of a direct proportion is equal to this constant (k); if (k) is greater than 1 or less than 1, the slope will reflect that but still indicate a direct relationship.
Do only linear equations have a slope?
No, slopes are not exclusive to linear equations. While linear equations have a constant slope, non-linear equations can have a varying slope that changes at different points along the curve. For example, the slope of a quadratic or exponential function can be determined using calculus, specifically by finding the derivative of the function at a given point. Thus, while all linear equations have a defined slope, many non-linear equations also have slopes that can be analyzed at specific points.
