# Non linear relationship worksheets

### Year 8 Plotting linear relationships

MAWM. uses deductive reasoning in presenting arguments and formal proofs. MANA. sketches and interprets a variety of non-linear relationships. Worksheet – Linear and Nonlinear Relations. Name: Complete the following questions on this worksheet and check the answer key on the final page before. Number and Algebra. Plotting linear relationships and examples of linear relations Non-linear relationships are discussed in greater detail in other modules.

Is it always going to be 5? If it's always going to be the same value, you're dealing with a linear function.

## Graphing Simple Non-Linear Relationships (9)

If for each change in x--so over here x is always changing by 1, so since x is always changing by 1, the change in y's have to always be the same.

If they're not, then we're dealing with a non-linear function. We can actually show that plotting out. If the changes in x-- we're going by different values, if this went from 1 to 2 and then 2 to what you'd want to do, then, is divide the change in y by the change in x, and that should always be a constant.

## Linear equations and functions

In fact, let me write that down. If something is linear, then the change in y over the change in x always constant. Now, in this example, the change in x's are always 1, right?

So in this example, the change in x is always going to be 1. So in order for this function to be linear, our change in y needs to be constant because we're just going to take that and divide it by 1. So let's see if our change in y is constant.

When we go from 11 to 14, we go up by 3.

When we go from 14 to 19, we go up by 5, so I already see that it is not constant. We didn't go up by 3 this time, we went up by 5. And here, we go up by 7. And here, we're going up by 9. So we're actually going up by increasing amounts, so we're definitely dealing with a non-linear function. And we can see that if we graph it out. So let me draw-- I'll do a rough graph here.

So let me make that my vertical axis, my y-axis.

And we go all the way up to So I'll just do 10, 20, Superposition principle does not apply to the systems characterized by non-linear equations. The input and output of a non-linear system is not directly related. We have learned some techniques to solve linear equations. Solutions to non-linear equations are also possible, but they are comparatively difficult and more involved. Some interesting Topics related to Equations: Next we discuss a few interesting things about equations.

Kids your age might wonder as to how they can draw: A simple linear equation is of the form: We learn some easy ways to graph a linear equation in one or two variables. Graphing a linear equation in one variable: Graphing an equation requires a co-ordinate plane.

It consists of two straight lines one in horizontal direction and the other in the vertical direction.

The horizontal line is referred to as x-axis and the vertical line is called y-axis. The point where the two lines intersect is called origin.

A simple coordinate plane has been shown below.
