In this seventh- and eighth-grade math worksheet, students will use the form y = kx to write the equations for proportional relationships based on several given tables. This important skill prepares students to problem solve with real-world proportional relationships, while also preparing learners to eventually write linear equations from tables.When X is two, Y is zero times X. While, when X is four, Y is one times X. And when X is six, Y looks to be, 1 and 1/3 times X. So you don't have the same proportionality constant the entire time. So, we have zero proportional relationships depicted here. So I would pick zero there. Let's do one more example.

Proportion says that two ratios (or fractions) are equal. Example: We see that 1-out-of-3 is equal to 2-out-of-6. The ratios are the same, so they are in proportion. Example: Rope. A rope's length and weight are in proportion. When 20m of rope weighs 1kg , then: 40m of that rope weighs 2kg. 200m of that rope weighs 10kg.
