# Determine The Equation of a Line

Lesson Objective
This lesson shows you how to determine the equation of a line using the given information such as the slope, coordinates of a point and more.
In this lesson, we will learn how to determine the equation of a line using the information given.

This lesson will show you 2 examples on how to do so using the following information:
1. Point (2,5) and Slope = 2
2. Points (1,4) and (2,1)
You can proceed by reading the study tips first or watch the math video or try out the practice questions.

# Study Tips

Tip #1
You need to have some knowledge on Slope-Intercept Form of a line. You can learn about it by watching the math video in this lesson.
Tip #2
Usually, to determine the equation of a line, we should begin with the Slope-Intercept Form of a line (as shown in the picture).

Next, we just use the information given to find the slope (m) and the y-intercept (b).

However, bare in mind that the information given may not directly help us to find the slope or y-intercept. If this is the case, we need think of way of using the information to find them.
