This is a Clilstore unit. You can .

**We have just watched a video about linear functions, now we are going to do a fill in the gaps exercise, at the end of the lesson you could find the exercise, please click on FILL IN THE GAPS button.**

**Now, you should watch the video again and compare your answers.**

**Work in pairs, you have to give some definitions, after watching the video.**

**dependent variable:**

**independent variable:**

**linear function:**

**slope:**

** Next step....**

Next step....We are going to use Geogebra, we have to click on the geogebra button, then we are going to draw some functions. Let's take the worksheet 3 and correct the second exercise.

**Finally, there is a summary about linear function:**

A linear function is a function of the form . The graph of a linear equation is a graphic view of the set of all points that make the equation true. The graph of any linear function is a straight line. f(x)=mx+b

A linear function can be represented in two ways, standard form and slope-intercept form. Standard form is a formal way of writing a linear equation, while slope-intercept form makes the equation easier to graph.
