Easy Guide: Plotting Straight Line Graphs Step by Step

Understanding Straight Line Graphs: A Comprehensive Guide explores the fundamental concepts of plotting straight line graphs step by step and understanding gradient and y-intercept in graphs.

• The guide thoroughly explains how straight line equations follow the format y = mx + c, where m represents the gradient and c is the y-intercept
• Detailed instructions are provided for plotting points by substituting x-values to find corresponding y-values
• The relationship between gradient values and line steepness is explored, including positive and negative gradients
• Methods for how to find the equation of a line from a graph are demonstrated through practical examples

Page 2: Finding Equations from Graphs

This page focuses on practical applications of straight line concepts, particularly in determining the equation of a line from its graph. The method of calculating gradients using two points on a line is explained in detail.

Definition: The y-intercept is the point where the line crosses the vertical y-axis.

Example: To find the gradient between points 1,11,1 and 3,53,5: m = changeinychange in y/changeinxchange in x = 5−15-1/3−13-1 = 2

Highlight: When finding the equation of a line, first calculate the gradient using two points, then identify the y-intercept by looking at where the line crosses the y-axis.

Vocabulary:

  • Change in y: The vertical distance between two points
  • Change in x: The horizontal distance between two points
  • Points: Specific locations on a line represented by coordinates

Page 1: Understanding Straight Line Equations and Gradients

This page introduces the fundamental concepts of straight line graphs and their equations. The coordinate system is explained with the x-axis being horizontal and the y-axis being vertical. The standard form of a straight line equation y = mx + c is thoroughly explored through practical examples.

Definition: A straight line equation follows the format y = mx + c, where m is the gradient and c is the y-intercept.

Example: For the equation y = 3x + 2:

  • When x = 0, y = 2
  • When x = 1, y = 5
  • When x = 2, y = 8

Highlight: The gradient mm determines the steepness of the line. A larger gradient creates a steeper line, while a negative gradient means the line slopes downward.

Vocabulary:

  • Gradient: The measure of steepness in a line
  • Y-intercept: The point where the line crosses the y-axis
  • Coordinates: Points on the graph represented as x,yx,y

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
