In a table, divide a number in one column by the corresponding number in the other column. In a graph it is the gradient of the line. The equation, for the variables X and Y will be of the form Y = mX and the constant of proportionality is m.

How do you find constant in math?
The answer depends on what the constant is: the y-intercept in a linear graph, constant of proportionality, constant of integration, physical [universal] constant.
What are the characteristics of proportional relationships?
Direct proportions may be represented by a straight line through the origin, with the equation y = kx. The gradient of the line is the constant of proportionality and is a measure of the change in the "dependent" variable for a unit change in the "independent" variable. In the case of an inverse proportionality, the graph is a hyperbola with the equation y = k/x. The constant of proportionality, k, is a measure of the change in the reciprocal of the "dependent" variable for a unit change in the "independent" variable.
When y varies directly as x what is true of the variables x and y?
y = cx where c is some non-zero constant of proportionality. Equivalently, x = ky where k (= 1/c) is a constant of proportionality. The graph of y against x is a straight line through the origin, with slope c.
What relationship exist between two variables when their ratio is constant?
Direct proportionality. Their graph would be a straight line through the origin, with the slope equal to the ratio.
How do you find the equation of a graph?
You find the equation of a graph by finding an equation with a graph.

What does a direct proportion look like on a graph?
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
What type of equation has a graph that is a vertical line?
x = constant.
What is the graph of the equation is paralleled to y axis?
x=constant
Is a constant acceleration graph a linear equation?
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
Graph the equation and identify the y-intercept y equals 5x-7?

A function wahose graph is parabola?
Any equation where variable a = some multiple of variable b2 + constant will graph a parabola.
When y varies directly as x what is true of the variables x and y?
y = cx where c is some non-zero constant of proportionality. Equivalently, x = ky where k (= 1/c) is a constant of proportionality. The graph of y against x is a straight line through the origin, with slope c.
What does a velocity and time graph look like?
indirect proportionality
