The Equation of a Line and how to construct an Equation
![]() How many lines can you spot on the picture of the beautiful landscape? Do they all go into the same direction? What will the equation of those lines be? An important aspect of a successful and confident mathematician, is the ability to construct equations. As part of coordinate geometry you are therefore required to be able to construct linear equations in various situations. To be able to do so properly, you need to understand what a general equation looks like and what each part/term of the equation stands for. I will therefore start with explaining to you what the gradient-intercept form is. Make sure to already have a solid understanding of what the gradient of a line is and how to calculate it. At the end of this section you will be able to construct equations of all the lines in the picture. Good luck and have fun!
