How do you find if two things are directly proportional without a graph.
To find if two things are directly proportional without a graph, you can use this formula:
y = kx
where x is one variable, y is the other variable, and k is a constant.
If the values of y increase or decrease as the values of x increase or decrease, and k remains constant, then the two variables are directly proportional.
For example, if you are given a table of values and asked to determine if two variables, x and y, are directly proportional, you can find the value of k by calculating the ratio of y to x for any pair of corresponding values in the table. If this ratio is constant for all values of x and y, then the variables are directly proportional.
