How does Constant Ratio Work

Question

How do you find a constant ratio on a graph?

Answer 1

You can find the constant ratio of a linear function by finding the slope of a line.

The slope formula is y subscript 2 - y subscript 1 divided my X subscript 2 and x subscript 1.

For example, here are two ordered pairs of a given line: (1, 1) and (3, 3).

(x1, y1) and (x2, y2)

3-1/3 -1 = 1. So, the constant ratio is 1 which equal the slope of this line.

y = 1x.
