What else can I help you with?
Does y equal 1X show direct variation?
Yes. y = 1x is the same as y = x which is the simplest case of direct variation. If you consider the equation y = mx + b, then a direct variation will always have b = 0 (i.e. the graph goes through the origin). The value of m is called the "constant of variation", and the equation is usually written as y = kx.
Is the equation 3x - 5 equals y an example of direct variation?
-2
What is the Mathematical relation between energy of radiation and wavelength?
The energy of a basic unit of electromagnetic energy, the photon, is related directly to its frequency by a scaling factor called Planck's Constant, and the equation is often written e = Hf where e is energy unit, H is Planck's Constant and f is frequency unit.
If the equation of a line has an undefined slope and passes through the point (13) which form would be used to write the equation?
If a line has an undefined slope, it is vertical. The equation of a vertical line passing through the point (13) is written as ( x = 13 ). This indicates that for all points on the line, the x-coordinate remains constant at 13, while the y-coordinate can take any value.
Definition of proportion in math Correct answere?
A proportion is an equation written in the form Proportion stating that two ratios are equivalent. In other words, two sets of numbers are proportional if one set is a constant times the other.
What is inverse variation?
Two variables, x and y are in inverse variation if x*y = c for some constant c. The equation can be written in the form y = c/x.
Does y equal 1X show direct variation?
Yes. y = 1x is the same as y = x which is the simplest case of direct variation. If you consider the equation y = mx + b, then a direct variation will always have b = 0 (i.e. the graph goes through the origin). The value of m is called the "constant of variation", and the equation is usually written as y = kx.
Why can't the constant of variation equal zero?
Suppose the two variables, x and y were directly proportional, with the constant of variation c. Their relationship would be written as y = cx then if c = 0 you get y = 0x = 0 So y = 0 and it would no longer be a variable.

What is the equation of direct variation if y is 16 when x is 20?
The equation can be written as y = 16x/20 which can be simplified to y = 4x/5
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 Mathematical relation between energy of radiation and wavelength?
The energy of a basic unit of electromagnetic energy, the photon, is related directly to its frequency by a scaling factor called Planck's Constant, and the equation is often written e = Hf where e is energy unit, H is Planck's Constant and f is frequency unit.
How can you determine if a linear relationship is a direct variation from an equation?
Suppose the variables are X and Y and the equation can be written in either of the following equivalent forms: bY = aX or aX - bY = 0 or Y/X = c where a, b and c are non-zero constants.

What are equation of lines?
y = mx + cWhere m is the gradient of the line and c is a constant (the intercept of the line).The equation of a line is typically written asy=mx+b where m is the slope and b is the y-intercept.If you know two points that a line passes through, this page will show you how to find the equation of the line.
