Describe methods you can use to show a proportional relationship between two variables, x and y. for each method, explain how can you find the unit rate and the slope

Table of values: The ratio of y to x gives the unit rate and slope. Equation: If the equation can be written as

y = mx, then m is the unit rate and the slope. Graph: When the line passes through the origin, then the value of r at the point (1, r) is the unit rate and the slope.

Step-by-step explanation:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
